S8P4 Waves Review 2

Front

A high-frequency wave has ___________ than a low-frequency wave.

Back

a shorter wavelength.

Front

Of the waves listed below, which has the longest wavelength and, therefore, the lowest frequency and the least energy? Microwaves, Ultraviolet Rays, Gamma Rays, X-rays.

Back

Microwaves.

Front

Which of the following occurs as the frequency of a wave decreases? The wavelength does not change in response to frequency changes. The wavelength decreases as the frequency decreases. The wavelength increases and then decreases as the frequency decreases. The wavelength increases as the frequency decreases.

Back

The wavelength increases as the frequency decreases.

Front

Of the visible spectrum, what color has the highest frequency? Blue, Green, Yellow, Red, Violet.

Back

Violet.

Front

Which of the figures best represents reflection? A, B, C, D.

Back

B.

Front

What is the relationship between frequency and wavelength in waves?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What type of wave is characterized by oscillations perpendicular to the direction of wave travel?

Back

Transverse wave.

Front

What type of wave is characterized by oscillations parallel to the direction of wave travel?

Back

Longitudinal wave.

Front

What is the speed of a wave if its frequency is 10 Hz and its wavelength is 2 meters?

Back

Speed = frequency × wavelength = 10 Hz × 2 m = 20 m/s.

Front

What is the term for the bending of waves around obstacles or through openings?

Back

Diffraction.
