a line is two rays put together
A ray is normal and perpendicular to the wave front. Shortly, that's the difference.
Infrared radiation is of a much lower frequency (and a longer wavelength) than X-rays.
A ray of light which strikes the surface is called incident ray and a surface which is reflected is called a reflected ray
yes
The normal
a ray continues on and on but a line segment stops
A ray begins at an endpoint and extends in only one direction.A half line does not include the endpoint.
a line has a dot on each end and a ray only has one dot and an arrow, it keeps on going.
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.
i think that normal is a line segment and normal ray is a line with an arrow head like vector to point in a certain direction....
A ray has a single start point, and goes on infinitely in one direction. A line segment has two end points and is finite. A line has no end points and goes on infinitely in two directions.
line: it goes on for infinity. <---------> line segment: has 2 endpoints, does not continue. -------- ray: starts at one point, then goes on for infinity. --------->
there is no difference.
A line segment has a end point. A ray goes on forever until it hits something, like another ray.
A ray is normal and perpendicular to the wave front. Shortly, that's the difference.
Yes there is a large difference between the two. A line has no end and a line segment ends.
The normal line divides the angle between the incident ray and the reflected ray into two equal angles.
