Question

describing kinds of energy
use the drop - down menus to identify the type of energy each phrase describes.
the shortest wavelength of visible light
energy that can be felt as heat but not seen
short, invisible rays that can cause eye damage
visible light with the longest wavelength

Explanation:

1. Visible light spectrum ranges from red (longest wavelength) to violet (shortest wavelength); D corresponds to violet/blue end, so it is the shortest visible wavelength.
2. Thermal IR (Infrared, labeled B) is invisible but felt as heat.
3. Ultraviolet (labeled C) are invisible rays that can damage eyes.
4. Visible light's longest wavelength is red, which corresponds to label A.

Answer:

1. The shortest wavelength of visible light: D
2. Energy that can be felt as heat but not seen: B
3. Short, invisible rays that can cause eye damage: C
4. Visible light with the longest wavelength: A
