Waves

Question 1

Longitudinal

Answer 1

Direction of wave travels in is parallel to direction of energy transfer
Sound, Seismic P

Question 2

Transverse

Answer 2

Direction of oscillation is perpendicular to direction of energy transfer
EM, seismic S
EM waves travel at the same speed in a vacuum

Question 3

Stationary Wave Formation:

Answer 3

Two progressive waves of same frequency and wavelength, similar amplitude, travelling at the same speed in opposite directions superpose

Question 4

Changing Mediums

Answer 4

Frequency stays the same
Wavelength and speed change

Question 5

Total Internal Reflection Conditions

Answer 5

1. Wave is travelling from a higher refractive index to a lower refractive index
2. Angle of incidence is greater than the critical angle

Question 6

Diffraction

Answer 6

When waves pass through a gap of similar size to their wavelength, they spread out. (change amplitude)
Gap size = Wavelength, more prominent diffraction
