1. If the period of a wave is 0.27s, how many waves would pass by in 1.0 minute?

Question

2. When a wave from of light passes through an opening that's large compared to its wavelength, it:
a) behaves as a single new point source
b) produces a straight wave front, curved backwards at the ends
c) produces spherical patterns of waves
d) none of the above

Answer 1

1. 60s. * 1Wave/0.27s. = 222 Waves.
