Wave Transmission, Reflection & Absorption

Front

What is wave transmission?

Back

Wave transmission is the process by which waves travel through a medium, such as air, water, or solid materials.

Front

What is reflection in terms of waves?

Back

Reflection is the bouncing back of waves when they hit a barrier or surface, such as sound waves echoing off canyon walls.

Front

What is absorption in the context of sound?

Back

Absorption is the process by which sound waves are taken in by materials, reducing the amount of sound that is reflected.

Front

What causes sound to occur?

Back

Sound is caused by vibrations that create pressure waves in a medium.

Front

What type of wave is sound?

Back

Sound is a mechanical wave that requires a medium (solid, liquid, or gas) to travel.

Front

What is the relationship between frequency and pitch?

Back

Frequency is the number of waves that pass a point in a given time, and it determines the pitch of the sound; higher frequency means higher pitch.

Front

What happens to sound waves in a vacuum?

Back

Sound waves cannot travel in a vacuum because there are no particles to transmit the vibrations.

Front

Why do some rooms have soft materials on the walls?

Back

Soft materials reduce sound reflection and absorb sound, making the room quieter.

Front

What is an echo?

Back

An echo is a reflection of sound that arrives at the listener after a delay.

Front

What type of wave is light?

Back

Light is an electromagnetic wave that can travel through a vacuum.
