Think about it ...

Why don't we just use solar energy for all our needs?

Multiple Choice

What is the relationship between heat energy and wavelength?

• As the wavelength decreases, the energy decreases

• As the wavelength decreases, the energy increases

• As the wavelength increases, the energy remains the same

Multiple Choice

You have learned that the temperature of the sun is very high. It emits

radiation in the form of short waves because they carry a lot of energy.

Which law explains this relationship between temperature and wavelength?

• Wien's Law

• Stefan-Boltzmann's Law

• Planck's Law

Multiple Choice

What amounts of the total solar radiation are absorbed by Earth's surface and

atmosphere, respectively?

• Earth's atmosphere absorbs 48 percent of net solar radiation as it approaches Earth, and

  its surface absorbs 23 percent

• Earth's atmosphere absorbs 23 percent of net solar radiation as it approaches Earth, and

  its surface absorbs 48 percent

• Earth's atmosphere absorbs 17 percent of net solar radiation as it approaches Earth, and

  its surface absorbs 5 percent

Multiple Choice

Consider a scenario in which a car is left parked outside a mall during the

afternoon. After a few hours, the temperature inside the car is higher than

the temperature outside the car. Which phenomenon or effect must have

caused this?

• higher solar radiation

• global warming

• greenhouse effect

Multiple Choice

Which gases cause the greenhouse effect, warming up Earth's atmosphere?

• oxygen, nitrogen

• methane, carbon dioxide, water vapor, ozone, and nitrogen dioxide

• methane, carbon monoxide, nitrogen, ozone, and hydrogen

Match

Match the description with the appropriate law of radiation.

• Every object emits radiation of all wavelengths

• Objects emit distinct wavelengths from the spectra at different temperatures.

• The relationship between an object's temperature and the amount of radiation it emits predicts the amount of energy Earth and the sun radiate.

• A good absorber is also a good emitter of radiation at the same wavelength.

Planck's Law

Wein's Law

Stefan-Boltzmann Law

Kirchoff's Law

• Planck's Law

• Wein's Law

• Stefan-Boltzmann Law

• Kirchoff's Law
