Science Waves Unit Part A 8th gr 24-25

Front

What happens to the speed of sound as it travels from a gas to a solid?

Back

The speed increases.

Front

What is the effect of adding energy to a wave?

Back

It shows higher wave amplitudes.

Front

What property of a sound wave changes when the volume is increased?

Back

Amplitude.

Front

What is diffraction in the context of light waves?

Back

Light bends around an object.

Front

What is the relationship between wavelength and frequency in waves?

Back

As wavelength increases, frequency decreases.

Front

Define amplitude in the context of waves.

Back

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

Front

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium to travel through, while electromagnetic waves do not.

Front

How does temperature affect the speed of sound in air?

Back

The speed of sound increases with an increase in temperature.

Front

What is the principle of superposition in wave theory?

Back

When two or more waves overlap, the resulting wave is the sum of the individual waves.

Front

What is the definition of a wave?

Back

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