Refraction law:
For a wavefront travelling by a boundary among two media, the first along a refractive index of n1, and the other with one of n, the angle of incidence theta is associated to the angle of refraction phi by
n1 sin theta = n2 sin phi.

Explain about Atoms Atoms - having of a nucleus (central core) and orbiting electrons. Nucleus have protons (+ particles) and neutrons (neutral particles). Neutral atoms have
Q. State the law of conservation of electric charges? The entirety charge in an isolated system always remains constant. For instance Uranium ( 92 U 238 ) can decay by emittin
Choroid: Inside the sclera it is thin, non transparent or opaque. Its front part of iris there is an aperture known as the pupil which control amount of light entering the eye.
Visible Radiation (Waves): Visible waves have a wavelength range among 400 and 700 nanometre.
Why diffraction can't occur if slit width is less than the wavelength of the light? Can you explain?
