Where do x-rays fall on the electromagnetic spectrum?

Back

X-rays are located between ultraviolet light and gamma rays on the electromagnetic spectrum.

Front

What is the significance of the HR Diagram?

Back

The HR Diagram (Hertzsprung-Russell Diagram) is a scatter plot of stars showing the relationship between their absolute magnitudes or luminosities versus their stellar classifications or effective temperatures.

Front

What type of star is the Sun classified as?

Back

The Sun is classified as a Yellow Star.

Front

What is the relationship between a star's color and its temperature?

Back

A star's color indicates its temperature; blue stars are the hottest, followed by white, yellow, orange, and red stars.

Front

What are gamma rays?

Back

Gamma rays are the highest frequency electromagnetic waves, found at the far right of the electromagnetic spectrum.
