Why does light from the sun melt the plastic when light from the desk lamp does not

Because the sun gives off a type of light that carries energy, and light from the desk lamp does not.

Explanation:

All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.

Lamps are electrical devices that use electrical energy in the form of electrical current.

Step-by-step explanation:

First, find the mean:

+5.65.2+4.6+4.9+5.7+6.4

          by

           6=5.4

Now find the sum of the differences between the mean and all the points. Square those results:

5.6-5.4=.04

5.2-5.4=.04

4.6-5.4=.64

4.9-5.4=.25

5.7-5.4=.09

6.4-5.4=1

find the average of the differences:

.04+.04+.64+.25+.09+1

      by

   6 =.343
