Edexcel A level Physics (Waves) June
2024 Exam Questions and Answers
100% Pass
Wavelength - Answer>>*The displacement between a point on
a wave and the identical point on the next wave*
Period - Answer>>*The time taken for one complete oscillation*
Frequency - Answer>>*The number of complete oscillations in
one second*
f = 1/T
v = fλ
Amplitude - Answer>>*The maximum displacement from the
mean position*
Phase - Answer>>The position of a point on a wave at a
specific moment in time
Transverse Waves - Answer>>*Direction of oscillation is
perpendicular to the direction of propagation of the wave*
Transverse waves are composed of particles that make up the
wave oscilating up and down
Longitudinal Waves - Answer>>*Direction of oscillation is
parallel to the direction of propagation of the wave*
A longitudinal wave is composed of areas of compression (high
pressure) and rarefaction (low pressure) caused by particles
oscillating backwards and forwards
Wavefront - Answer>>*A line joining points at the same position
along a wave*
, Coherance - Answer>>*Waves which have are of the same
frequency, wavelength, polarisation and in a constant phase
relationship*
Path Difference - Answer>>*the difference in distance from
each source to a particular point*
If wave source is coherent can be used with the phase of the
waves to see how the waves will interfere.
Path difference of a whole number of wavelengths gives complete
constructive interference, path difference with an extra half a
wavelength gives complete destructive interference
Superposition - Answer>>*when two or more waves of the
same type meet at a point the resultant displacement of will be
the sum of the individual displacements*
Interference - Answer>>A special kind of superposition where
the waves are coherant
Standing Wave - Answer>>A standing wave is formed when a
wave and it's reflection superpose to form areas of complete
destructive interference (nodes) and complete constructive
interference (anti nodes)
One standing wave was 2 ovals in it.
The fundamental frequency has oval in it
Equation for speed of a transverse wave on a string -
Answer>>V = √T/µ
Diffraction - Answer>>*The change in direction of a wave when
it passes through a gap of similar size to it's wavelength*
