9. Wave Phenomena (AHL)

Question 1

Simple harmonic motion =

Answer 1

motion where the acceleration/force is proportional to the displacement from a fixed point and is directed towards the fixed point

Question 2

 Resolution =

Answer 2

the ability of an imaging system to be able to produce two separate distinguishable images of two separate objects.

Question 3

 Rayleigh criterion =

Answer 3

two sources are just resolved if the central maximum of the diffraction pattern of one source falls on the first minimum of the other.

Question 4

 Resolvance of a diffraction grating =

Answer 4

the ratio of the average wavelength to the range in wavelengths.

Question 5

 The Doppler effect =

Answer 5

the apparent change in the frequency of a wave when there is relative movement between the source and the observer.
