Course Hero is not sponsored or endorsed by any college or university. Thank you for helping me for my igcse exams. Any object on the surface of the water (e.g. Based on the way in which these waves travel . Amplitude is the height of the wave, usually measured in metres. Note that the frequency of the wave will remain constant. Wave Fronts: Imaginary lines that join all in-phase particles of waves. EDEXCEL IGCSE / CERTIFICATE IN PHYSICS 3-3. gamma Gamma waves are used for heating up food. General waves. However, the waves speed, direction and wavelength will change. S.No Transverse Waves 1. We're on a mission to end educational inequality for young people everywhere. Waves can be longitudinal, in the case of . Your email address will not be published. Other waves are transverse. A wave hits a boundary between two media and does not pass through, but instead stays in the original medium, The angle of incidence = The angle of reflection, When waves reflect off a barrier, the angle of reflection, r, is equal to the angle of incidence, i, A wave passes a boundary between two different transparent media and undergoes a change in direction, Waves can change direction when moving between materials with different densities, Diffraction: when a wave passes through a narrow gap, it spreads out. Thank you guys! In longitudinal waves, the displacement of the medium is parallel to the propagation of the wave i.e. As well the International Baccalaureate Diploma Program, Business . In a longitudinal wave (such as sound), the particles vibrate parallel to the direction of the wave. The ray bends towards the normal. Revision for CAIE Physics IGCSE, including summary notes, exam questions by topic and videos for each module. Thus, microwaves are used phenomenally in information transmission back and forth to the satellite. Edexcel Specification Section 3: Waves d) Light and sound understand that light waves are transverse waves which can be reflected, refracted and . Topic 4: Electricity and Magnetism. micro(waves)/ Infrared (IR) Radio waves have the highest frequency. You guys are amazing! E.g. Click here to go back to the previous topic. Longitudinal wave are ones in which the displacement of the particle is parallel to the direction of wave motion. We apologise for the inconvenience, but hope that the new images will provide you with an even better learning experience. Aripple on a pondand awave on a stringare examples of this. More details. They travel in a straight line and do not carry an electric charge with them. Describe wave motion in terms of amplitude, wavelength, frequency and period. The water is denser than air (water molecules are more closely packed together than air molecules), so the speed of the wave decreases, and so does its direction. Rather, individual particles vibrate (oscillate) about fixed positions instead. Wavelength - The distance between identical points in the adjacent cycles of crests of a . Answer Notes Marks 6 (ci) Diffraction; And one of The incoming wave spreads out at the gap; The energy carried by the wave spreads out ; allow: diffraction seen in (cii) recognisable spelling for 'diffraction' ignore: the wave gets bigger wave is bent (wavefront is) curved 2 Topic 1: General Physics.

The frequency of a wave is the number of waves produced each second. Diffraction Diffraction is the process by which waves spread out as a result of passing through a narrow gap or across an edge of an object. A wave transfers energy from one place to another without the transfer of particles in the medium. Resource type: Unit of work (no rating) 0 reviews. Click here to register your spot to contribute to Backnotes, In a transverse wave, it is the distance between two adjacent peaks or troughs, In a longitudinal wave, it is the distance between two adjacent compressions or rarefactions, This is a bit tricky to measure for longitudinal waves, But for transverse waves, it is simply the distance between the rest position to the peak. so very useful for the exam, Wow this is really helpful. If you continue to use this site we will assume that you are happy with it. This leads to compressions (particles are closer together than normal) and rarefactions (particles are further apart than normal).

REFRACTION IN A GLASS BLOCK When a ray of light goes from air to glass, it is refracted. For the electronic transition from n = 3 to n = 5 in the hydrogen atom. Know that for a transverse wave, the direction of vibration is at right angles to the direction of propagation and understand that electromagnetic radiation, water waves and seismic S-waves (secondary) can be modelled as transverse, Know that for a longitudinal wave, the direction of vibration is parallel to the direction of propagation and understand that sound waves and seismic P-waves (primary) can be modelled as longitudinal. Water travels more slowly in shallow water compared to deep water. Edexcel Specification Section 3: Waves b) Properties of Waves understand the difference between longitudinal and transverse waves and describe . It is denoted by the letter f and is measured in hertz (Hz). Thank you guys, One of the best website . The edge of the unit cell is 408 pm. This can be from one crest to the next crest or from one trough to the next trough. They will be replaced shortly. Diffraction can also occur as waves hit the edge of a barrier. They are used to capture the human skeleton defects. ( For FCC , edge = r 8 ), For the electronic transition from n = 2 to n = 4 in the hydrogen atom. For transverse waves, the displacement of the medium is perpendicular to the direction of propagation (pulsing) of the wave i.e. The angle between the incident (original) wave and the normal (the perpendicular bisector to the barrier) will be equal to the angle between the reflected wave and the normal. to IGCSE to physics 0625 General Wave Properties Waves A wave transfers energy from one place to another without the transfer of particles in the medium. The wavelength of a wave is the distance between a point on one wave and the same point on the next wave i.e. . The frequency of a wave is the number of waves produced each second. End of preview. A ripple tank has a vibrating bar which can generate waves of varying frequency in water. B People further from the volcano heard the sound later than people nearer to the volcano. Katie has always been passionate about the sciences, and completed a degree in Astrophysics at Sheffield University. The IGCSE AID Team is based in the little state of Kerala in South India. When a wave hits a rough plane barrier, it is mostly refracted; the wave bends and travels through the plane barrier instead of reflecting (see P8.2 Refraction of Light). When waves reflect off a plane barrier (like a mirror) there is no travelling through a different medium, so the density of the medium is the same, which means that the speed and wavelength of the waves remain the same. Waves in a fluid can be observed using a ripple tank. Recall and use the equation for wave speed v = f ? These include ampli. Reflection When waves hit a plane surface, it willreflectoff it. Chromium metal crystallizes as body-centered lattice. sound reflecting from a wall. radio waves travelling from an Earth satellite to the Moon. content based on Edexcel syllabus,however, appropriate for other boards too.
