Question

A periodic wave travels from one medium to another. Which pair of variables are likely to change in the process?Select one of the options below as your answer:A. velocity and wavelengthB. velocity and frequencyC. frequency and wavelengthD. frequency and phaseE. wavelength and phase

Answer 1

Answer;

A. velocity and wavelength

Explanation;

• When a wave travels from one medium to another it undergoes refraction which results to the change in direction.
• Refraction of a wave is one of the property of waves that occurs when a wave changes direction when it passes from one medium to another. This occurs as a result of bending of the wave which occurs since the mediums involved are of different density and refractive index.
• Apart from the change in direction, refraction is accompanied by the change in wavelength of a wave and thus a change in speed.

Answer 2

Answer:

Velocity and Wavelength

Explanation:

I got an A on the test. and your welcome.
