6. WHAT DO LENS DO TO LIGHT WAVES? HOW DOES THE SHAPE OF THE LENS AFFECT THE LIGHT?

here

Explanation:

There is an easy way to remember how light rays travel through lenses. Light rays passing through a lens always bend toward the thickest part of the lens. Light waves bend toward the thick center in a convex lens. They bend out toward the thick edge in a concave lens.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
