- The incident ray, the refracted ray and the normal to the surface at the point of incidence all lie in one plane.
- For any two given pair of media, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant.
- The above law is called Snell's law after the scientist Willebrod Snellius who first formulated it
Thus
Where m is the refractive index of the second medium with respect to the first medium.
for e.g.
the refractive index of glass with respect to air is given as
ratio of -speed of light in air to speed of light in glass.(when light passes from air to glass)

What happens when a light moves from a material with a lower index of refraction to another material with a higher index of refraction?
The ray of light bends towards the normal.
What happens when light passes into a material where the speed of light is lower?
It moves at a slower speed!
Air moves from where pressure is higher to lower or lower to higher?
Higher to lower.
What happens if light moves from a material in which its speed is lower to one in which its speed is higher the ray is bent away from the?
The ray bends away from the "normal" a line that runs perpendicular through the boundary of the two materials.
What does the atom do when the electron moves from lower to higher energy level?
it loses energy

It moves at a slower speed!
What happens when light moves from a material in which it's speed is higher to a material in which it's speed is lower?
-- its speed decreases -- its wavelength increases -- if it doesn't approach the boundary perpendicular to it, then it bends closer to the perpendicular
Air moves from where pressure is higher to lower or lower to higher?
Higher to lower.

When an electron in an atom moves from a lower energy state to a higher state?
An electrons moves from lower energy to higher energy when it is excited.
What cloud moves higher at night and lower during the day?
higher durning the day and lower during the night
Does a atom absorb light when it moves from a lower orbit to higher orbit?
It does take energy to move a atom lower state to a higher state. This form of energy could be in the spectrum of light. This could also be in other forms of energy. ie heat thru gamma rays,
How can astronomers determine whether a star is moving towards or away from earth?
Astronomers determine whether a star is moving toward or away from the Earth via the Doppler effect. Imagine a motorcycle moving past you. As it drives towards you, it has a higher frequency, and a lower frequency when it drives away. The same thing happens with light. As an object moves towards us, its light has a higher frequency and lower wavelength - this is called blueshift. As an object moves away from us, its light has a lower frequency and higher wavelength - this is called redshift.

What layer moves higher at night and lower in the day?
Ionosphere
Light is emitted as an electron transitions from a higher energy orbital to a lower energy orbital How long does it take for the actual transition to take place?
It takes no time as electrons can not exist in an inbetween state of charge
