1. o ray obey snail law of refraction,
e ray does not obey
2. velocity of o ray is same for all direction,
velocity of e ray is diffrent for diffrent direction.
3. for o ray wavefront is spherical,
for e ray wavefront is elliptical.
4. ve>vo for negative crystal.
5. vo >ve for positive crystal.
incident ray-the light ray striking a reflecting surface is called the incident ray. reflected ray-the light ray obtained after reflection from the surface, in the same medium in which the incident ray is travelling , is called the reflected ray.
A line extends infinitely in both directions, a ray in only one. A ray can be shown by drawing a small arrow above the name of the ray, with the arrow pointing in the direction of the ray.
a line has a dot on each end and a ray only has one dot and an arrow, it keeps on going.
It is a difference of scale. Interplanetary means between planets; it takes a ray of light minutes or hours to go from a planet to another planet. Intergalactic means between galaxies; it takes a ray of light hundreds of thousands of years, or even millions of years, to travel that distance.
A light beam or beam of light is a narrow cone of light energy radiating from a small source. In optics, a ray is an idealized narrow beam of light.
In case of some crystals such as calcite, when light is passed through two rays come out giving rise to two images. One is found to be stationary and the other one is moving around the first as we rotate the crystal about the line of incidence. The stationary image is known as ordinary image and the moving image is extraordinary image. The stationary image is due to ordinary ray and extra ordinarily moving image is due to extra ordinary ray. Ordinary ray obeys all the laws of refraction where as the extra ordinary does not do so. This is because the light entered into the crystal has been polarized.
there is no difference.
A ray is normal and perpendicular to the wave front. Shortly, that's the difference.
no eagle in the name
Infrared radiation is of a much lower frequency (and a longer wavelength) than X-rays.
a ray continues on and on but a line segment stops
the fins.
A ray of light which strikes the surface is called incident ray and a surface which is reflected is called a reflected ray
The skate has a different body structure then a ray.
The difference between a ray and a skate is that their reproductive stratigies are totally different. skates can not sting you but sting rays can! i have tried touching ones tail it didn't sting me!!
blu-ray players are much more high quality. Blu-ray disks can only be played on a blu-ray player or ps3 The main difference is in the quality. However, if you're looking into getting a blueray player, most of the ones on the market today will also play your DVD's so you don't have to have two separate players taking up extra space.
