Question

Part 1 Assume that as a wave travels from one particular medium to another, its speed decreases. What happens to the wave's frequency?A.  Its frequency increases.B.  Its frequency decreases.C.  Its frequency remains the same.D.  It is impossible to determine without more data.Part 2Which best explains the correct answer to Part 1?A.  A wave's frequency always remains the same. B.  A wave's frequency is inversely proportional to its speed.C.  Given that the wave's wavelength remains the same, if the wave's speed decreases, then the frequency must decrease.D.   Given that a wave's speed is equal to the product of its wavelength and frequency, the wavelength must be known to determine the frequency.

Answer 1

Answer:

Part 1

C. Its frequency remains the same.

Part 2

A. A wave's frequency always remains the same.

Step-by-step explanation:

The relationship between wavelength, frequency, and speed is given as:

`v=\lambda f`

When the frequency of a wave increases, its wavelength also increases.

The speed of a wave does not change as its frequency changes, and vice-versa.

Therefore, as the speed of the wave decreases, its frequency remains the same

A wave's frequency always remains the same regardless of the speed and wavelength
