There is a form of light that is very energetic and can cause damage to living cells and tissues. The Sun emits this type of light, but much of it is blocked by ozone in the atmosphere. Because this type of light can be so damaging to cells, it is often used to kill bacteria in drinking water. The light is shined on contaminated water, and this makes the water clean and healthy for drinking. What type of light is this?
