You are sitting on a dock watching water waves as they pass. you noticed at 5 waves to pass by certain spot every 20 seconds you also noticed at the crest of the water line up exactly with two points that are 6 m apart.

A) what is the frequency of these waves?
B)what is the wavelength of the waves described above?
C) what is the velocity of the waves from where u are watching?
Please show ur wor

A) 0.25 Hz

B) 6 m

C) 1.5 m/s

Explanation:

The number of waves that pass a certain spot every 20 seconds = 5 waves

The distance between the crest = 6 m

A) The frequency of the wave, f = The number of cycles per second = 5/20 = 0.25 per second = 0.25 Hz

B) The wavelength of the wave, λ = The distance between crests = 6 m

C) The velocity of the wave, v = f × λ = 0.25/s × 6 m = 1.5 m/s.

where’s the list ? the question is incomplete

your answer is, orbit around the nucleus
