Question

look at the diagram showing the different wavelengths in sunlight.
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.

Explanation:

Electromagnetic waves with wavelengths greater than 700 nanometers are infrared waves. Infrared radiation is associated with thermal energy (heat). Ultraviolet waves (shorter than visible light) cause skin cancer/sunburn. Waves >700nm are long, not short, and are invisible to human eyes (visible light is ~400-700nm).

Answer:

A. They take the form of heat.
