We get a variety of radiation from the sun. Not just visible light, but we also get other radiation like X-rays, microwaves, radio waves, infrared rays, and ultraviolet rays. Ultraviolet rays or UV rays have higher frequency, and thus more energy than visible light. So when these energetic UV rays from the sun reach us, they can penetrate our skin and cause damage to our skin cells.

There are two types of UV rays that reach us: UVA and UVB. UVA are the lower frequency, longer wavelength rays, while UVB are the higher frequency, shorter wavelength ones.

On reaching our skin, these rays can have harmful effects like skin cancer, skin aging, sunburn and tanning. So we use sunscreen for protection. Sunscreens absorb and reflect these rays and prevent them from reaching our skin when we are out in the sun. But what about being indoors? Do we still need to wear sunscreen indoors? Tune in to this BYJUs Mistaken Science video to find out.
