6th Grade Waves Review

Front

What is reflection in the context of waves?

Back

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

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs of a wave.

Front

What type of waves require a medium to travel?

Back

Mechanical Waves require a medium (like air, water, or solid materials) to pass.

Front

What does the letter 'A' represent in wave properties?

Back

The letter 'A' typically represents amplitude, which is the height of the wave from its rest position.

Front

What do waves transfer?

Back

Waves transfer energy.

Front

What is amplitude?

Back

Amplitude is the maximum distance that the wave moves from its rest position.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

What is the difference between mechanical and electromagnetic waves?

Back

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

Front

What is the formula for calculating wavelength?

Back

Wavelength (λ) can be calculated using the formula: λ = v/f, where v is the speed of the wave and f is the frequency.
