Question

Select the statement(s) that are true about light and absorption.

The black soil at the base of the plant absorbs all seven colors of light.

Visible light is a form of electromagnetic radiation that travels to Earth from the sun.

The leaves reflect green light and absorb red, orange, yellow, blue, indigo, and violet light.

When light is absorbed by an object, the light energy is converted into another form of energy, usually thermal energy.

The red flowers are absorbing the red light and reflecting the orange, yellow, green, blue, indigo, and violet light.

Answer 1

True:
- The black soil at the base of the plant absorbs all seven colors of light. (Black surfaces absorb most visible wavelengths and convert them to heat.)
- Visible light is a form of electromagnetic radiation that travels to Earth from the sun.
- The leaves reflect green light and absorb red, orange, yellow, blue, indigo, and violet light. (Chlorophyll reflects green and absorbs mainly red and blue; other pigments change exact absorption, but leaves generally reflect green and absorb most other visible wavelengths.)
- When light is absorbed by an object, the light energy is converted into another form of energy, usually thermal energy.

False:
- The red flowers are absorbing the red light and reflecting the orange, yellow, green, blue, indigo, and violet light. (Red flowers reflect red and absorb most other colors.)
