what is a real image
an image that forms where rays converge
what is a focal point
the point where light rays paralelle to the optical axis converge after being reflected by a mirror or refracted from a lens
what is a virtual image
an image that forms from light rays that diverge or chnage direction
what is the law of reflection
when a wave is reflected from a surface the angle of reflection is equal to the reflection of incidence
absorption
the tranfer of energy from a wave too the medium through which it travels
transmission
the passage of light through a medium
diffraction
change in direction of a wave when it travels by the edge of an object or through an opening
transparent
a material that allows almost all of the light striking it to pass through and through which objects can be seen clearly
diffusion
the movement of substances from an area of higher concentration to an area of lower concentration
convex lens
thicker in the middle, and is called a converging lens
angle of reflection
the angle of reflection is the angle between the normal and reflected ray
electromagnetic spectrum
radio waves, microwaves, infrared waves, ultra violet waves, x-rays, gamma rays
vacuum
a space with nothing in it
radient energy
