Front

What happens to the energy of an electromagnetic wave if its wavelength is longer?

Back

Energy is lower.

Front

In main sequence stars, how does temperature relate to absolute brightness?

Back

The star with the greater temperature will have a higher absolute brightness.

Front

What property is used to classify radiation in the electromagnetic spectrum?

Back

What is Apparent Magnitude?

Back

The brightness of a star when viewed from Earth.

Front

What is Convection?

Back

When less dense material rises and cooler material sinks.

Front

What is the relationship between wavelength and energy in electromagnetic waves?

Back

Longer wavelengths correspond to lower energy.

Front

What is the significance of a star's temperature in determining its color?

Back

Hotter stars appear blue, while cooler stars appear red.

Front

What is Absolute Magnitude?

Back

The true brightness of a star at a standard distance.

Front

How does the electromagnetic spectrum relate to visible light?

Back

Visible light is a small part of the electromagnetic spectrum.

Front

What is the effect of distance on the apparent brightness of a star?

Back

The farther away a star is, the dimmer it appears.
