Year 9 Waves

Front

What is the most powerful wavelength?

Back

X-rays/Gamma rays are the most powerful wavelengths.

Front

What type of interference occurs when waves combine to make a larger wave?

Back

Constructive interference occurs when waves combine to make a larger wave.

Front

What is the term for the number of waves that pass a fixed point in a given amount of time?

Back

Frequency is the number of waves that pass a fixed point in a given amount of time.

Front

What is the relationship between frequency and wavelength?

Back

High frequency waves have low wavelength.

Front

What is the distance from one point to the next corresponding point on a wave called?

Back

Wavelength is the distance from one point to the next corresponding point on a wave.

Front

What is the term for the maximum displacement of a wave from its rest position?

Back

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

Front

What is the speed of a wave?

Back

Wave speed is the distance a wave travels in a given amount of time.

Front

What is the formula for wave speed?

Back

Wave speed = frequency × wavelength.

Front

What type of waves require a medium to travel through?

Back

Mechanical waves require a medium to travel through.

Front

What are the two main types of waves?

Back

The two main types of waves are mechanical waves and electromagnetic waves.
