If the ray hits the mirror at an angle of 30 degrees with the mirror surface, the complementary angle that the ray makes with the normal (perpendicular) to the mirror at the point of incidence is (90 - 30) = 60 degrees and since angle of incidence is equal to angle of reflection in a plane mirror, the angle of reflection is 60 degrees.
The law of reflection: When a ray of light reflects off a mirror, the angle of the incidence ray is equal to the angle of the reflection ray. Therefore, an incidence ray of 45 degrees will have a reflection ray of 45 degrees. As both rays are equal, either side of the normal line, then adding both angles equals 45 + 45 = 90 degrees. The normal line is a line perpendicular to the surface of the mirror.
The movement of one anterior surface towards another anterior surface, except in the case of the knee where it is posterior to posterior (Humans Only)
Basic math its 45 degrees.....if its 90 degrees and its coming in 45 such as a picture frame, then the degrees left is 45.....
Downward motion is defined as the movement of one's center of gravity towards the performance surface.
The wind correction angle for a true course of 30 degrees, with an airspeed of 300, with a wind direction of 90, and with a wind speed of 50, is -8.3 degrees. The indicated course must then be 21.7 degrees. CCORRECTION = sin-1 (VWIND sin (CWIND - CACTUAL) / VINDICATED)
The law of reflection: When a ray of light reflects off a mirror, the angle of the incidence ray is equal to the angle of the reflection ray. Therefore, an incidence ray of 45 degrees will have a reflection ray of 45 degrees. As both rays are equal, either side of the normal line, then adding both angles equals 45 + 45 = 90 degrees. The normal line is a line perpendicular to the surface of the mirror.
The angle of reflection is equal to the angle of incidence. It will be at 30o to the surface of the mirror (from the opposite edge) ^ This answer is not correct for SURFACE, but is correct for RELATIVE ^
This problem can be answered one of two ways. The easy answer is 150 degree The other answer is to create a 360 degree model in you head or on a digram of the equation. When an angle is entered onto a surface that is flat it is only half of the circle or 180 degrees. Then because it enters at the 30 degree angle its trajectery on its way out is then again 180 degrees minus the 30 of entry leaving the same 150 degrees.
28 degrees on surface and gradually decreasing towards depth.
Because a reflection reverses the direction of the component of the wave vector of the light hitting the reflecting surface which is orthogonal to the surface. The component parallel to the surface will not change. This means the light going towards a mirror, will go away from the mirror after reflection. But if it went from the left to the right, it will continue to go from the left to the right. Same with up and down. In three dimensions this is the same as changing the handedness of the image.
A convex surface means bulging out surface. A convex mirror is that spherical mirror in whichthe reflection of light takes place at the bulging out surface.A spherical mirror which is polished from hollow side, such that its reflecting surface is towards outer sideis called convex mirror.

Quick Answer:The angle of incidence is not equal to the angle of refraction.The angle of incidence is equal to the angle of reflection.Better Answer:(This answer applies to all waves, e.g. sound, ripples, earthquakes, but the answer is given in terms of light waves.)The angle of incidence never equals the angle of refraction except in the peculiar circumstance when there is an interface between two materials of exactly the same index of refraction.The angle of refraction is the direction of the wave exiting the surface and the angle of incidence is the angle entering the surface.These two angles are related by Snell's law and by Snell's law one would conclude that the index of the medium of the incident beam would be exactly the same as the index of the transmitted beam. In optical terms, it would mean the wave propagates as though there were no interface and the two mediums were actually the same medium. In that case, there would be no reflection as well.So, one does not expect this to happen, not because it can't, but because the wave travels through the surface as though the surface did not exist and that is both unusual and uninteresting.
A reflected wave is a wave that bounces off a surface. For example, if you throw a stone in a pond, reflected waves occur when the ripples meet the shore and begin to travel back towards the stone.
The duties of intellectuals towards society is to mentor the young boys and act responsibly as they are the reflection of a given society.
Yes, now we can - there are windows that have channels in them that divert fifty percent of their incident light towards photovoltaic materials in the window frame. As well there are a dozen other means of Solar Photon capture.
