Ch. 24: Light, Astronomical Observations, and the Sun

Gravity is a form of electromagnetic radiation.

• False

• True

Electromagnetic radiation includes-

• Gamma Rays

• Radio Waves

• Visible Light

• X-Rays

• All of the above

The energy of a photon depends on its-

• Wavelength

• Size

• Mass

• Rate of Movement

What does a prism do to white light?

• Separates it into several colors

• Reflects it completely

• Makes it invisible

Isaac Newton unknowingly discovered-

• Spectroscopy

• The sun

• The moon

• Water

A star's spectrum tells its-

• Chemical composition

• Age

• Size

• None of the above

The Doppler Effect refers to how-

• a change in wavelength that occurs when an object moves toward or away from a source

• objects under a gravitational pull dopple over

• light waves are separated by a prism

Large Doppler shifts show-

• High speeds

• Low speeds

• No movement

A refracting telescope uses-

• Objective lens

• mirror

• prism

• spectroscope

This scientist is famous for making astronomical observations with telescopes.

• Galileo

• Einstein

• Newton

• Mozart
