Does Sunlight Reflected Off A Mirror Increase The Temperature Of The Sun-rays?
Answers
Answer:
your answer is here !
Explanation:
A standard planar mirror will not increase the energy contained in the rays that reflect off it. In fact, there will be some loss of energy since the reflective surface is not perfect. There is some reduction in the light's intensity as it passes through the mirror's glass and reflects off the backing surface.
Parabolic mirrors, on the other hand, focus and concentrate the light rays on a single point in front of the mirror, aptly named the focus. Although the energy is not amplified, it will be effectively increased because of the additive effect that will result when the light energy is concentrated....

If the surface where the reflected sunlight incident also received sunlight directly from the sun, the answer is yes. Because the sunlight heat energy is due to the infra red radiation present in it will be double. If by using another nirror and allow its reflected beam incident on the same surface, then the amount of heat would three times the amount of heat on the same surface by the direct sunlight, If heat energy is increased naturally its temperature will also be increased.
