Example Questions

Example Question #1 : Waves

What is the wavelength of a  wave if its velocity is ?

Possible Answers:

Correct answer:

Explanation:

The relationship between wavelength and velocity is given by the equation;

The question gives us the velocity of the wave and its frequency. Using these values, we can solve for the wavelength.

Example Question #1 : Optics, Waves, And Quantum

What best describes how a wave is affected when it travels from one medium to another medium?

Possible Answers:

Neither speed not frequency change

The wave speed changed, but the frequency remains the same

Both speed and frequency change

The frequency changes, but the speed remains the same

The wavelength does not change

Correct answer:

The wave speed changed, but the frequency remains the same

Explanation:

It is a property of waves that the frequency remains constant and speed changes as it passes from one medium to another.
