Front

What color of light bends the most when passing through a prism?

Back

Violet bends the most due to its shorter wavelength.

Front

What are the small bright markings on the sun’s photosphere called?

Back

Sunspots are the small bright markings on the sun’s photosphere.

Front

What do we call meteoroids that strike Earth?

Back

Meteoroids that strike Earth are called meteorites.

Front

In which direction does a comet’s tail point?

Back

A comet’s tail points away from the sun.

Front

What is the relationship between the energy of a photon and its wavelength?

Back

The energy of a photon is inversely related to its wavelength; shorter wavelengths have higher energy.

Front

What is a prism?

Back

A prism is a transparent optical element that refracts light, separating it into its constituent colors.

Front

Define sunspots.

Back

Sunspots are temporary phenomena on the photosphere of the Sun that appear as spots darker than the surrounding areas.

Front

What is the difference between a meteoroid, meteor, and meteorite?

Back

A meteoroid is a small rocky or metallic body in outer space; a meteor is the flash of light produced when a meteoroid enters the Earth's atmosphere; a meteorite is a meteoroid that survives its passage through the atmosphere and lands on Earth.

Front

What causes the tail of a comet to form?

Back

The tail of a comet forms when it approaches the sun, causing the ice to vaporize and dust to be released, which is then pushed away by solar wind.

Front

What is the significance of wavelength in electromagnetic radiation?

Back

Wavelength determines the type of electromagnetic radiation and its energy; shorter wavelengths correspond to higher energy.
