use a ruler to measure the length. use a protractor to measure the angle of incidence. i dont think there is any other way to measure a ray. unless you are talking about the angle which you most likely arent since the question clearly states 'ray'.

How do you measure the angles of incidence and reflection?
They are the angles made by the incident ray and the reflected ray with the line perpendicular to the reflecting surface at the point of reflection.
What is the difference between incident ray and the reflected ray?
incident ray-the light ray striking a reflecting surface is called the incident ray. reflected ray-the light ray obtained after reflection from the surface, in the same medium in which the incident ray is travelling , is called the reflected ray.
What is angle of incident if the reflected ray is 90 degree to incident ray?
The angle of incident is 45 degrees. The incident and reflected ray have the same magnitude and if the sum of the magnitudes is 90 degrees the incident is 45 degrees.
Why incident ray and emergent ray are parallel to each other in the refraction of light?
Because both incident ray and emergent ray have same slope.
Why should the ray emerging from the glass block come out parallel to the incident ray?
The ray comes out parallel to the incident ray because the ray has the opposite refraction as when it entered the block.

What are incident and reflected rays?
incident ray: the ray that strikes the object reflected ray: the ray that is directed away from the object
What is angle of incident if the reflected ray is 90 degree to incident ray?
The angle of incident is 45 degrees. The incident and reflected ray have the same magnitude and if the sum of the magnitudes is 90 degrees the incident is 45 degrees.
Why can the refracted ray can also be the incident ray?
It only happens when the incident ray is shone at 90 degrees. The refracted ray will then travel along the same path as the incident ray. This is known as total internal refraction.
The incident ray and the emergent ray will always be?
The Incident ray, falling on the glass slab, and the Emergent ray will always be parallel to each other.
What is difference between incident ray and a reflected ray?
A ray of light which strikes the surface is called incident ray and a surface which is reflected is called a reflected ray
The angle of incidence is the angle between the incident ray and the?
The angle of incidence is the angle between the incident ray and the normal (perpendicular) to the reflecting surface.
Why incident ray and emergent ray are parallel to each other in the refraction of light?
Because both incident ray and emergent ray have same slope.
Why should the ray emerging from the glass block come out parallel to the incident ray?
The ray comes out parallel to the incident ray because the ray has the opposite refraction as when it entered the block.
How is an incident ray related to a reflected ray?
The relation between the incident ray and reflected ray is described by the material which is reflecting the incident ray. depending upon the material used the incident ray is scattered or reflected or refracted or transmitted or absorbed. For example if you take rainbow the sun light is incident on the rain drop , it reflected back of drop several times and due to that we get the rainbow with various colours.
How do you measure angle of incidence and angle of reflection?
the angle of incidence is the angle measured between the normal and the incident ray.. the angle of reflection is the angle measured between the reflected ray and the normal..
