Wave Behaviors

What is refraction?

• The bending of light as it passes from one medium to another.

• The reflection of light off a surface.

• The scattering of light in different directions.

• The absorption of light by a material.

What is diffraction?

• The bending of light as it passes through a prism.

• The spreading out of waves when they pass through a narrow opening or around obstacles.

• The reflection of waves off a surface.

• The absorption of waves by a medium.

What happens to most of the light that hits a window?

• The light is being absorbed.

• The light is being reflected.

• The light is being transmitted.

• The light is being scattered.

What is the speed of a wave?

• The distance a wave travels in a given amount of time.

• The frequency of the wave multiplied by its wavelength.

• The amplitude of the wave divided by the time period.

• The total energy carried by the wave.

What causes the separation of white light in a prism?

• Diffraction

• Reflection

• Refraction

• Dispersion

Why does a purple shirt appear purple?

• It reflects all wavelengths of color equally.

• It absorbs all wavelengths of color except the purple wavelength.

• It emits purple light when exposed to sunlight.

• It is dyed with a special chemical that changes its color.

What is a medium?

• A type of wave

• The substance through which a wave can travel.

• A measurement of frequency

• A method of sound amplification

What is a standing wave?

• A wave that appears to be stationary, formed by the interference of two waves traveling in opposite directions.

• A wave that travels in one direction only without interference.

• A wave that changes amplitude over time due to external forces.

• A wave that is reflected back on itself, creating a loop.

What is transmission?

• The passing of light through a medium.

• The reflection of sound waves.

• The absorption of heat by a surface.

• The scattering of particles in a gas.

What is the relationship between wavelength and frequency?

• As wavelength increases, frequency decreases.

• Wavelength and frequency are directly proportional.

• Increasing frequency leads to longer wavelengths.

• Wavelength has no effect on frequency.
