1
Q

Simple harmonic motion =

A

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

2
Q

 Resolution =

A

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

3
Q

 Rayleigh criterion =

A

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

4
Q

 Resolvance of a diffraction grating =

A

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

5
Q

 The Doppler effect =

A

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