It is called the angle of refraction. It varies subject to wavelength, relative medium properties and relative media motion.
(often considered as frequency, but that is to forget that while frequency is the 'observable' it is only a derivative of wavelength and time ('speed' is distance/time and always relative to some datum - also often forgotten).
Angle of refraction
The normal
The angle of incidence is the angle between the incident ray and the normal (perpendicular) to the reflecting surface.
The angle between the incident ray and the normal is known to be angle of incidence The angle between the reflected ray and the normal is said to be angle of reflection By the law, the angle of incidence = angle of reflection
When a ray of light from a medium is incident on another medium with different optical density, the ray bends due to refraction. The perpendicular distance between the emergent ray and the incident ray is called the lateral shift. The angle which the incident ray makes with the normal is called angle of incidence denoted by 'i' and the angle made by the refracted ray with the normal is called the angle of refraction denoted by 'r'. Lateral shift is given by the formula:- Where t is the thickness of the glass slab, i is the angle of incidence and r is the angle of refraction
the angle between the refracted ray and the normal
Angle of refraction
the angle between the refracted ray and the normal
The normal
it is the angle between the direction of the incident ray and the refracted ray.
The angle of incidence is the angle between the incident ray and the normal (perpendicular) to the reflecting surface.
Yeah or yeha
The angle between the incident ray and the normal is known to be angle of incidence The angle between the reflected ray and the normal is said to be angle of reflection By the law, the angle of incidence = angle of reflection
The angle between the incident ray and the normal is known to be angle of incidence The angle between the reflected ray and the normal is said to be angle of reflection By the law, the angle of incidence = angle of reflection
terms realated to refraction of light are * interface * incident ray * refracted ray * point of incidence *normal *angle of incidence * angle of refraction *angle of deviation
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..
If a beam of light enters a substance with a higher density than air and at an angle, the light is refracted so that an object on the far side of the substance appears to be closer to the observer. If the density of the substance is lower than that of air, the light is refracted away from the observer and the object being viewed appears to be farther away.
