Physical Science Semester Exam Review-Waves

Front

What is the fastest medium for light to travel?

Back

A vacuum.

Front

What phenomenon occurs when a wave bends around an obstacle?

Back

Diffraction.

Front

What happens to the amplitude of a sound wave when its energy increases?

Back

The amplitude increases, causing the sound to get louder.

Front

What is the relationship between wavelength and frequency in the electromagnetic spectrum?

Back

As the wavelength decreases, the frequency increases.

Front

What is the law of reflection?

Back

The angle of incidence is equal to the angle of reflection.

Front

What type of wave is sound?

Back

Sound is a mechanical wave.

Front

What is the difference between transverse and longitudinal waves?

Back

Transverse waves oscillate perpendicular to the direction of wave travel, while longitudinal waves oscillate parallel to the direction of wave travel.

Front

What is refraction?

Back

Refraction is the bending of a wave as it passes from one medium to another.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation.

Front

What is the speed of light in a vacuum?

Back

Approximately 299,792 kilometers per second (km/s).
