During a beach outing, prolonged exposure to the sunlight can cause sunburn and even worse, skin cancer. Why is this the case when visible light does not harm us?

• The sun’s radiation comes with infrared light which has a lower frequency and therefore carries higher energy that damages the skin compared to visible light

• The sun’s radiation comes with ultraviolet light which has a higher frequency and therefore carries higher energy that damages the skin as compared to visible light

• The sun’s radiation comes with gamma rays which have very high frequency and therefore carry immense energy that pierces through the skin, unlike visible light

• The sun’s radiation comes with ultraviolet light which has a lower frequency and therefore carries lower energy that damages the skin as compared to visible light
