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:

• Option 1: Electromagnetic waves with wavelengths greater than 700 nanometers are infrared waves. Infrared radiation is often associated with heat.
• Option 2: Ultraviolet (UV) rays (wavelengths less than 400 nm) can cause skin cancer and sunburn, not the waves with wavelengths > 700 nm.
• Option 3: Waves with wavelengths greater than 700 nm are not the shortest. For example, radio waves have much longer wavelengths.
• Option 4: Visible light has wavelengths between approximately 400 - 700 nm. Waves with wavelengths > 700 nm are not visible to the human eye.

Answer:

They take the form of heat.
