Waves

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 reflection in terms of waves?

Back

Reflection is when a wave strikes an object and bounces off, like an echo.

Front

What is a medium in the context of waves?

Back

A medium is the matter through which energy moves, such as air, water, or solid materials.

Front

What type of wave requires a medium to travel?

Back

Mechanical waves require a medium to travel.

Front

What is transmission in wave behavior?

Back

Transmission is when a wave travels through an object (medium) without changing direction.

Front

What is absorption in wave behavior?

Back

Absorption occurs when a medium takes in a wave and the wave's energy is completely transferred.

Front

What are mechanical waves?

Back

Mechanical waves are waves that require a medium to travel, such as sound waves.

Front

What are electromagnetic waves?

Back

Electromagnetic waves are waves that do not require a medium to travel, such as light waves.

Front

What is refraction?

Back

Refraction is the bending of a wave as it passes from one medium to another, changing its speed.

Front

What is the difference between longitudinal and transverse waves?

Back

In longitudinal waves, the particle movement is parallel to the wave direction; in transverse waves, it is perpendicular.
