Unit 4- Energy

What happens to the solar energy absorbed by plants during photosynthesis?

• It is recycled by the plant and returned to the atmosphere.

• It is converted into oxygen and glucose.

• It is stored as heat within the plant for cellular functions.

• It is transformed into chemical energy.

All waves transmit energy not ________________.

What is the best explanation of the relationship between frequency and energy in transverse waves?

• The lower the frequency, the greater the energy it holds.

• The longer the wavelength, the greater energy it holds.

• The greater the number of waves per second, the greater the energy it holds.
