Waves: Sound and Light Unit

Front

According to the law of reflection, the angle of ________ is always equal to the angle of _________.

Back

incidence, reflection

Front

In which medium does light travel the slowest?

Back

Solid

Front

When you see a color, you are seeing what is REFLECTED. Provide an example about this statement.

Back

For example, if you see green on a plant leaf, the wavelengths of the color GREEN from visible light spectrum bounce off the plant to your eye. So you see GREEN.

Front

Put the mediums in order from fastest to slowest in terms of the speed of SOUND:

Back

Solid, Liquid, Gas

Front

Stars moving away from the Earth results in a phenomenon called __________.

Back

Red shift

Front

What is the speed of sound in air at room temperature?

Back

Approximately 343 meters per second.

Front

What is the difference between transverse and longitudinal waves?

Back

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

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another due to a change in speed.

Front

What is the visible spectrum?

Back

The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye, ranging from red to violet.

Front

What is the relationship between frequency and wavelength in waves?

Back

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