what do you think you know about physics, physics is the study of matter under the effect of energy, but does this includes solid states bodies, atoms at ground states, object at microscopic size or object moving faster than light? these and more is what prompt me to ask again what is physics?
light waves bend or refract at the ______between two media
the
reflection process takes place the boundary , when light a light reach a
boundary it changes from one medium to another, becausedifferent media have different refractive
index.
