Physical Science- Final 2nd Semester

Light energy travels as

• a wave

• a passenger

• a driver

• a particle

Some properties of light waves include frequency, wavelength, and amplitude.

• frequency, wavelength, and amplitude.

• frequency, and wavelength

• color and shape

• frequency and amplitude.

The_________________ of a light wave is the height of the wave, or intensity of the light.

• amplitude

• wavelength

• Frequency

The____________ is a measure of the distance the wave travels in one oscillation.

• wavelength

• Amplitude

• Frequency

The ____________of a light wave is a measure of the number of times the wave oscillates in one second.

• Frequency

• Amplitude

• Wavelenght

In a vacuum, light energy travels at the speed of light, which is

• 300, 000, 000­­ m/s.

• 300, 000­ m/s.

• 300, 000, 000­­ km/s.

When light travels through different media, such as air, water, or glass, it travels_________________depending on the type of material it passes through.

• at different speeds

• at same speeds

The trough of a wave is the lowest point of a wave below the equilibrium point.

• True

• False

The peak of a wave is the ____________ point of a wave above the equilibrium point.

• highest

• lowest

The height of the peak and the depth of the trough are both measured by the

• wave’s amplitude

• frequency
