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.
Can the angle of incidence be greater than the angle of reflection when plane mirror?
No, if the mirror is flat (a plane), the angle of incidence always equals the angle of reflection.
What happens to the light ray when the angle of incidence is greater than the angle of total reflection?
it is not the angle of total reflection, it is the critical angle. and when the angle of incidence is greater than the critical angle, total internal reflection takes place and as it is necessary for total internal reflection to take place that the ray must travel from denser to rarer medium so, when it occurs, the ray is reflected bach into the denser medium.
If the reflected beam is above the incident beam?
This indicates that the angle of reflection is greater than the angle of incidence, which typically occurs when light hits a surface at an angle and is reflected away from it. This is known as specular reflection and obeys the law of reflection.
The angle of incidence is always greater than the angle of reflection?
No, the angle of reflection is always equal to the angle of incidence according to the law of reflection. When light or other waves reflect off a surface, the angle they make with the normal (perpendicular line) to the surface upon reflection is the same as the angle they made with the normal upon incidence.
What is is the term for the phenomena observed when the incident angle is made greater than the critical angle?
Total internal reflection occurs when the incident angle is greater than the critical angle, causing light to be reflected back inside the medium rather than refracting out of it. This phenomenon is commonly seen in prisms and optical fibers.
What are the conditions of total internal reflection?
Total internal reflection occurs when a light ray traveling from a denser medium to a less dense medium strikes the interface at an angle greater than the critical angle. The critical angle is the angle at which the light ray is refracted along the interface. If the angle of incidence is greater than the critical angle, all of the light is reflected back into the denser medium.
Angle of refraction is less than 90 degree true or false?
False. You can have total internal reflection where the effective angle is greater than 90 deg
What happens when the angle of incidence is greater than the critical angle?
You get total internal reflection. That is, the incident beam bounces off the interface back into the medium.
How does total internal reflection depend on the angle of incidence of light rays?
Total internal reflection occurs when the angle of incidence is greater than the critical angle. The critical angle is the angle at which the refracted ray would be at 90 degrees to the normal. If the angle of incidence is less than the critical angle, the light ray will be refracted out of the material.
What is a angle greater than 180?
An angle greater than 180 degrees is a reflex angle
What are the conditions for total internal reflection to take place?
Light must travel from the optically denser medium to the optically less dense one. For total internal reflection to occur, the angle of incidence in the optically denser medium must be greater than the critical angle of that medium. The critical angle is that angle of incidence in the optically denser medium for which the angle of refraction is 90o.
