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.

What is reflected waves?
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.
What is the beam of light that travels towards the mirror called?
Incident ray or ray of incidence.
Which light is called the incident ray?
To be Specific, It would be the ray of light which is moving towards the medium.
Define concave and convex mirrors?
With Concave, the ends are "bent" towards you, making your reflection look short and stubby. With Convex, the ends are "bent" away from you making your reflection look tall and thinner
Example of total internal reflection?
rainbow rainbow is not example of tir bec. glory is an optical phenomenon produced by light backscattered (a combination of w:diffraction, reflection and w:refraction) towards its source by a cloud of uniformly-sized water droplets.
What will be the angle of reflection if a ray of light is incident towards a plane mirror at an angle of 30 degrees with the mirror surface?
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.
What will be the angle of reflection if a ray of light is incident towards a plane mirror at an angle of 45 degrees with the mirror surface?
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.
A ray of light is incident towards a plane mirror at an angle of 30-degrees with the mirror surfaceWhat will be the angle of reflection?
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 ^
Why does a reflection not preserve orientation of a figure on the plane?
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.
What are convex mirrors and how images look in it?
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. Example:-spoon

What are the duties intellectuals towards society?
The duties of intellectuals towards society is to mentor the young boys and act responsibly as they are the reflection of a given society.
Can you collect the light falling on a surface?
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.
What is The surface of the tooth that faces towards the hard palate?
Labial surface
When light passes through a prism why does the light ray bend towards the base of the prism?
reflection
What is the beam of light that travels towards the mirror called?
Incident ray or ray of incidence.
When do incident managers plan for the demobilization?
Incident managers begin planning for the demobilization when the project is about to be completed. This will be influenced by assessments that indicate that the project is on course towards completion.
