Remediation: SPS9 Waves and Light Formative Assessment

Front

What is a mechanical wave?

Back

A mechanical wave is a wave that requires a medium (solid, liquid, or gas) to travel through.

Front

What is an electromagnetic wave?

Back

An electromagnetic wave is a wave that can travel through a vacuum and does not require a medium.

Front

What is the relationship between amplitude and frequency in waves?

Back

Amplitude does not affect frequency; they are independent properties of a wave.

Front

What is refraction?

Back

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

Front

What is reflection?

Back

Reflection is the bouncing back of a wave when it hits a barrier or surface.

Front

What is diffraction?

Back

Diffraction is the spreading out of waves when they pass through a narrow opening or around obstacles.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (km/s).

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, the particle displacement is perpendicular to the direction of wave propagation, while in longitudinal waves, the displacement is parallel to the direction of wave propagation.

Front

What is the principle of superposition?

Back

The principle of superposition states that when two or more waves overlap, the resulting wave displacement is the sum of the individual wave displacements.

Front

What is the wavelength of a wave?

Back

The wavelength is the distance between two consecutive points that are in phase on a wave, such as crest to crest or trough to trough.
