S8P4 Waves Review 2

Front

What is reflection in the context of waves?

Back

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

Front

Which color in the visible light spectrum has the longest wavelength?

Back

Red has the longest wavelength in the visible light spectrum.

Front

What happens to the wavelength of a wave as its frequency decreases?

Back

The wavelength increases as the frequency decreases.

Front

What is the relationship between the incident angle and the reflected angle?

Back

The incident angle is equal to the reflected angle.

Front

Which type of wave has the shortest wavelength and the highest frequency?

Back

X-Rays have the shortest wavelength and the highest frequency among the listed options.

Front

Define wavelength in the context of waves.

Back

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

Front

What is frequency in relation to waves?

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz).

Front

How does the speed of a wave relate to its frequency and wavelength?

Back

The speed of a wave is equal to its frequency multiplied by its wavelength (Speed = Frequency x Wavelength).

Front

What is the visible light spectrum?

Back

The visible light spectrum is the portion of the electromagnetic spectrum that is visible to the human eye, ranging from violet (shortest wavelength) to red (longest wavelength).

Front

What is the difference between transverse and longitudinal waves?

Back

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