Look at the diagram showing the different wavelengths in sunlight.

i am on a !
which statement describes electromagnetic waves with wavelengths greater than 700 nanometers?

they take the form of heat.
they can cause skin cancer and sunburn.
they are some of the shortest waves.
they can be seen by human eyes as visible light.

Although light from the sun appears white, it is actually made up of a lot of different colors. this portion of the electromagnetic spectrum, we call white light is referred to as within the electromagnetic spectrum.

The speed of light in a material is 0.50 c. what is the critical angle of a light ray at the interface between the material and a vacuum?

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat
