If a wave hits a smooth surface at an angel of incidence of 40 degrees the angle of reflection is?

The angle of reflection is 40 degrees. The angle of incidence is equal to the angle of reflection.


What is the angle of incidence if the angle of reflection is 15 degrees?

If the ray is incident at right angles to the reflection surface, angle of Incidence will be 90 degrees and so will be the angle of reflection. In such a case, the incident ray, the normal and the reflected ray coincide.


When light is reflected is the angle of incidence at right angles to the angle of reflection?

Not usually. (Only when the angle is 45 degrees.)"The angle of incidence is equal to the angle of reflection."


True or false- the angle of incidence is always greater than the reflection angle?

False .According to laws of reflection, the angle of incidence is always equal to the angle of reflection.


What happens to the angle of reflected light rays as the angle of incident light rays becomes steeper?

The angle of incidence equals the angle of reflection. Therefore, if your angle of incidence is 15 degrees, your angle of reflection equals that also. If it is 45 degrees, your angle of reflection is also 45 degrees, and so on.


If light strikes a body of water at an angle of 55 degrees the angle of reflection will be what?

The angle of incidence is ALWAYS equal to the angle of reflection, therefore the degree of the angle reflection is 55 degrees.


What happens when the angle of incidence is equal to 90 degrees?

The angle of reflection will also be 90 degrees.


When is angle of incidence equal to angle of reflection?

The angle of incidence is ALWAYS equal to the angle of reflection! This is one of the laws of reflection.


What is the angle of reflection 20 degrees from the surface?

The key is to recognize that "the angle of INCIDENCE is equal to the angle of REFLECTION", for an 'Elastic' collision. So the answer is 20 degrees.


The angle of reflection is equal to the .......?

The angle of incidence


What is the size of the angle of incidence and reflection?

Angle of incidence can be anything. Angle of reflection is the same as angle of incidence.


If the angle of incidence is 23 degrees what would the angle of reflection be if the light was reflection be if the light was reflected from a plane mirror?

Also 23 degrees.
