Fall Semester 2025 Review - Part C

Heat transfer continues until both objects are at thermal equilibrium. 

• True
• False

Surfaces with ​ (a)   albedo generally warm up more easily than those with ​ (b)   albedo.

• low
• high

This is an example of a

• positive feedback loop

• negative feedback loop

Which of the following lists three greenhouse gasses?

• Methane, water vapor, and carbon dioxide.

• Methane, albedo, and carbon dioxide.

• Methane, infrared, and carbon dioxide.

• Methane, uranium, and carbon dioxide.

Greenhouse gasses

• reflect infrared light out of the atmosphere.

• absorb and re-emit visible light.

• absorb and re-emit infrared light.

• reflect visible light out of the atmosphere.

The photoelectric effect occurs when light shines on a metal and electrons are emitted. This only occurs if the light shining on the metal is:

• coherent.
• above a minimum intensity.

• above a minimum frequency.

• above a minimum wavelength.

Why can you see most objects?

• Light reflects off them

• Light is absorbed by them

• Light is bent by the object

Which region of the EM spectrum is responsible for giving you sunburn?

• radio

• microwaves

• infrared

• ultraviolet

Energy of a wave is ___________ proportional to its frequency.

• inversely

• directly

The source of all electromagnetic waves is 

• magnetic fields
• electric fields
• vibrating charged particles

• heat
