Question

while flying to Tucson, Mr H's plane experiences mild turbulence, causing the coffee to oscillate back and forth in his cup 4 times each second. if the coffee waves have a wavelength of 0.1m, what is their velocity across the surface?​

Answer 1

This question involves the concepts of wavelength, frequency, and velocity.

The velocity across the surface is "0.4 m/s".

Wave Speed

The velocity of the wave can be found using the following formula:

$v=f\lambda$

where,

• v = velocity = ?
• f = frequency = 4 Hz
• λ = wavelength = 0.1 m

Therefore,

v = (4 Hz)(0.1 m)

v = 0.4 m/s
