What is the difference between ultraviolet and visible radiation?

Expert Solution

There are many difference between 3 but most of the differences revolve around the fact that all of 3 have different wavelength & their order is - ultraviolet < visible < infrared . Similarly the order of frequencies & their energy is - Infrared < visible < ultraviolet .

Ultraviolet & infrared are invisible to our eyes whereas visible rays [ VIBGYOR ] is only radiation that is visible to us.

Ultraviolet rays are both useful & harmful . These are used in various biological experiments & researches . UV - A [one of the type of ultraviolet ) is needed for synthesis if Vit D in our body but its excess is harmful. UV- B & UV- C are harmful because they cause skin cancer, DNA damage, cataracts, etc.

Visible rays are needed to see various colours of our surroundings (as some parts of these rays get reflected & absorbed by various objects in different manner . we see only those colours which are reflected by object ) .
