Glass is ​ (a)   to visible light and to ​ (b)   infrared.

• transparent
• opaque
• albedo
• refract

If a graph looks like this, it could be representing a

• negative feedback loop

Glass is transparent to all wavelengths of light.

• True

• False

Consider the statement: "The amount of incoming solar energy is different at different latitudes."

What is meant by this statement?

• There is more solar energy coming into the Earth at the equator and less at the poles.

• There is more solar energy leaving the equator than the poles.

• There is more incoming solar energy on top of a mountain than in a valley.

• There is more incoming energy in Africa than in South America.

The photoelectric effect helps us to understand

• the particle nature of light.
• diffraction pattern produced as light passes through a single slit.
• the wave behavior of light.
• spectroscopes.

The shortest wavelength in visible light is______.

• violet

• red

• blue

• yellow

A light year is...

• The speed light travels
• How long it takes light to get to you from the sun
• The distance light can travel in a year
• How many years it takes light to be emitted

Which of the following are examples of ionizing radiation (choose 2).

• x-rays

• visible light

• gamma rays

• microwaves

Radiation is “ionizing” if it has enough energy to rip electrons off of atoms, creating ions.

• True

• False
