8th Grade Summative #4 part 2 Light Review

Front

What happens to frequency as wavelength increases?

Back

Frequency decreases.

Front

What is scattering in the context of light?

Back

Scattering is the process where light is forced to deviate from a straight path due to irregularities in the medium.

Front

How does the speed of sound waves change with increasing density of the medium?

Back

The speed of sound waves increases.

Front

What type of lens is used to converge light rays?

Back

Convex lens.

Front

What is the order of electromagnetic waves from shortest to longest wavelength?

Back

Gamma, X-ray, Ultraviolet, Visible, Infrared, Microwave, Radio.

Front

Define wavelength in the context of waves.

Back

Wavelength is the distance between successive crests of a wave.

Front

What is frequency in wave terminology?

Back

Frequency is the number of waves that pass a point in one second.

Front

Explain the concept of refraction.

Back

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

Front

What is absorption in terms of light?

Back

Absorption is the process where light is taken in by a material and converted to other forms of energy.

Front

What is the relationship between wavelength and energy of electromagnetic waves?

Back

As wavelength increases, energy decreases.
