a line is two rays put together
The angle of refraction is measured between the refracted ray and the normal line (perpendicular line) to the surface of the material at the point of incidence.
The angle of incidence is the angle between the incident ray and the normal (perpendicular line) to the surface the ray is striking.
A wavefront is a surface composed of points that are in phase with each other in terms of the oscillation of a wave. It represents the position of the wave at a specific instant. A ray, on the other hand, is a line that shows the direction of energy propagation of the wave. It represents the path along which the energy moves.
It is called the angle of incidence! Hope this helped! thank u it did
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
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.
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.
