What is a concave lens also known as?

• A diverging lens

• A converging lens

• A plano lens

• A cylindrical lens

What does pitch depend on?

• Amplitude

• Wave speed

• Frequency

• Volume

Amplitude is the maximum displacement on either side of the equilibrium (midpoint) position.

• True

• False

What is the definition of wave speed?

• to go in different directions from the same point

• the speed at which a wave travels through a medium

• the passage of a wave through a medium

• to move toward one point, approach nearer together

What occurs when an object causes a wave to change direction and bend around it?

• Absorption

• Converge

• Transmission

• Diffraction

What is the definition of converge?

• the speed at which a wave travels through a medium

• to move toward one point, approach nearer together

• A lens that is thinner in the center than at the edges

• to go in different directions from the same point

What is the definition of diverge?

• to go in different directions from the same point

• the point at which light rays parallel to the optical axis meet, or appear to meet, after being reflected or refracted by a mirror or a lens

• the process or action by which one thing absorbs or is absorbed by another

• an electromagnetic wave by which light travels through a medium or vacuum

What does ROY G BIV represent?

• Colors of the visible light spectrum in order of wavelength and frequency: red, orange, yellow, green, blue, indigo, violet

• the number of complete waves that pass a given point in a certain amount of time

• a tone's experienced highness or lowness; depends on frequency

• occurs when an object causes a wave to change direction and bend around it

What is light?

• an electromagnetic wave by which light travels through a medium or vacuum

• the process or action by which one thing absorbs or is absorbed by another

• to go in different directions from the same point

• the point at which light rays parallel to the optical axis meet, or appear to meet, after being reflected or refracted by a mirror or a lens

What is the definition of reflection?

• the process or action by which one thing absorbs or is absorbed by another. When a medium absorbs the wave's energy.

• The bending of a wave as it passes at an angle from one medium to another (like air to water, warm air cold air)

• the bouncing back of a ray of light, sound, or heat when the ray hits a surface that it does not go through

• the point at which light rays parallel to the optical axis meet, or appear to meet, after being reflected or refracted by a mirror or a lens.
