Question

what is one type of light that the sun emits but a light bulb does not?
□ gamma ray
□ x - ray
□ ultraviolet (uv)
□ visible
□ infrared (ir)
□ microwave
□ radio

Explanation:

A typical light bulb (incandescent, LED, etc.) mainly emits visible light, and may emit some infrared. The sun emits a wide spectrum including ultraviolet (UV) light, which light bulbs (especially common ones) do not emit in significant amounts (or at all for most household bulbs). Gamma rays from the sun are mostly absorbed by the atmosphere, X - rays from the sun are also largely absorbed, and microwaves/radio waves from the sun are not a primary emission that a light bulb lacks in the context of this question. Visible and infrared are emitted by light bulbs. So ultraviolet (UV) is a type of light the sun emits but a light bulb does not (in typical cases).

Answer:

ultraviolet (UV)
