Tyrel is learning about a certain kind of metal used to make satellites. He learns that infrared light is absorbed by the metal, X-ray light is transmitted through the metal, and visible light is reflected off the metal. Tyrel wonders of the metal will get warm if he shines the lights on it. Can light cause the metal to get warm?

The photoelectric effect causes the metals to get warm when light is shined on them.

Photoelectric effect:

It states that the metals emit electrons when by absorbing electromagnetic radiation.

When light sine on the metal, electrons present on the metals absorb some energy of the light or radiations and leave their atoms. This causes the metal to heat up when light sine on it.

The formula is,

Where,

- Plank's constant

-  Threshold frequency

- Energy needed to remove the electron

-  Kinetic energy of the emitted electron

Therefore, the metal gets warm due to the Photoelectric effect.

yes.

Explanation: The light that will be incidented on that metal is visible light.

It depends on 3 factors:

1. The temperature

2. The specific heat capacity of the metal

3. The thermal conductivity of the metal.

The metal getting warmer also depend on the reflection and the absorption of light energy in which it will surely absorb some energy and not reflect all.

When visible light is absorbed by an object, the object converts the short wavelength light into long wavelength heat. This causes the object to get warmer.
