Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is the medium in wave propagation?

Back

The medium is the substance through which a wave travels, such as air, water, or solid materials.

Front

What happens when light waves hit a transparent object?

Back

They pass through the object without being absorbed.

Front

What happens when light waves hit an opaque object?

Back

They are absorbed or reflected, preventing light from passing through.

Front

What is the visible light spectrum?

Back

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

Front

What is amplitude in relation to waves?

Back

Amplitude is the maximum extent of a wave's displacement from its rest position, related to the energy of the wave.

Front

How does frequency relate to sound?

Back

Frequency determines the pitch of a sound; higher frequency means a higher pitch.

Front

What is reflection in terms of waves?

Back

Reflection is the bouncing back of a wave when it hits a barrier.

Front

What is refraction?

Back

Refraction is the bending of waves as they pass from one medium to another due to a change in speed.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including visible light, radio waves, and X-rays.
