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.

The portion of a light ray that falls on a surface is?
The portion of a light ray that falls on a surface is incident ray.
What is difference between incident ray and a reflected ray?
An incident ray is the ray of light that approaches a surface, while a reflected ray is the ray of light that bounces off the surface after striking it. The angle of incidence of the incident ray is equal to the angle of reflection of the reflected ray, as per the law of reflection.
A reflected ray in a mirror makes an angle of 20 and deg with the incident ray. when the mirror is rotated 15 and deg what angle will the reflected ray now make with the incident ray?
The angle between the incident ray and the reflected ray is equal to the angle between the incident ray and the normal. When the mirror is rotated, the normal also rotates by the same angle. Therefore, the angle between the incident ray and the reflected ray will still be 20 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.
How is an incident ray related to a reflected ray?
An incident ray is the ray of light that strikes a surface, while a reflected ray is the ray that bounces off the surface. The angle of incidence (formed by the incident ray and the normal) is equal to the angle of reflection (formed by the reflected ray and the normal) according to the law of reflection.
Why can the refracted ray can also be the incident ray?
The refracted ray can coincide with the incident ray when light moves from one medium to another at a 90-degree angle relative to the boundary between the two media. This scenario leads to no bending of the light ray, resulting in the refracted ray following the same path as the incident ray.
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 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..
The ingoing ray of light?
The ingoing ray of light is the incident ray
