Front

What does the Sun supply to Earth?

Back

The Sun supplies light and heat to Earth.

Front

Why do distant stars appear dimmer?

Back

Distant stars appear dimmer even though they might be brighter than our own Sun due to their great distance from us.

Front

Which blocks will move if forces are acting on them?

What changes when you alter the pitch of a wave?

Back

When you change the pitch of the wave, the wavelength of the wave is changing.

Front

What is a wavelength?

Back

A wavelength is the distance between two consecutive peaks or troughs in a wave.

Front

What is amplitude?

Back

Amplitude is the height of a wave from its rest position to its crest or trough.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What is the role of the Sun in the solar system?

Back

The Sun provides energy in the form of light and heat, which is essential for life on Earth.

Front

What is the difference between light and heat?

Back

Light is electromagnetic radiation that is visible to the human eye, while heat is energy that is transferred due to temperature differences.
