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.
What will happen if the angle of incidence exceeds to the critical angle?
Then an interesting phenomenon called "Total internal reflection" takes place. Here the incident wave is totally reflected inside the medium as if it were reflected from the boundary of an opaque solid. For more details, contact at saqibahmad81@yahoo.com
Differentiate Angle of reflection from angle of incidence?
The 'normal' direction is the direction perpendicular to a surface. Think of a stick with one end of it glued to a mirror. When a beam of light or a tennis ball hits the surface, the 'angle of incidence' is the angle between the normal and the direction the ball came from. The 'angle of reflection' is the angle between the normal and the direction the ball will take after the bounce. The angle of reflection will be equal to the angle of incidence. Knowing this, you can always place your bank shot exactly where you want it to go after the bounce.
When light enters in medium 2 from medium 1 the angle of incidence is always greater than the angle of refraction Could total internal reflection take place from medium 1 to medium 2?
Definitely possible asmedium 2 is found rarer compared to medium 1
What is latitude equal to the?
The latitude of a place is the angle from the Earth's equator north or south to that place.
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.

What is an angle of incidence?
The angle of incidence is the angle formed between an incident ray and the normal (perpendicular line) to the surface that the ray strikes. It is a crucial measurement in understanding how light or other waves behave when they encounter a boundary or interface. The angle of incidence is equal to the angle of reflection when dealing with reflection phenomena.
Why total internal reflection takes place?
Total internal reflection occurs when light travels from a medium with a higher refractive index to one with a lower refractive index, at an angle greater than the critical angle. This phenomenon happens because at angles beyond the critical angle, the light is completely reflected back into the denser medium, rather than refracted out into the less dense medium.
What happens to light when its reflected?
According to law of reflection, the angle of incidence and angle of reflection are equal. If the incident surface is smooth specular reflection takes place where the light is reflected in a single direction.
How are angles measured in light experiments?
In light experiments, angles are typically measured in degrees using a protractor or other measuring devices. The angle of incidence, angle of reflection, and angle of refraction are key angles measured in experiments involving light. These measurements help scientists analyze how light behaves when it interacts with different surfaces or materials.
When light enters in medium 2 from medium 1 the angle of incidence is always greater than the angle of refraction Could total internal reflection take place from medium 1 to medium 2?
Definitely possible asmedium 2 is found rarer compared to medium 1
What is the angle of reflection when a beam of light strikes a curved mirror and has an angle of incidence of 40 degrees?
The angle of incidence equals the angle of reflection. Always. If the surface is curved, this is still true. Now for some caveats. 1. If the "beam" has zero width, then there really is no complication. Measure angles relative to the line perpendicular to the surface and in the plane of incidence at the point the beam strikes the surface and everything works out perfectly. 2. If the beam has a finite width, then everything still works out, but the beam strikes the surface at more than one point and the reflected beam goes away from the surface at more than one point but at each point, the angle of incidence equals the angle of reflection, but the angle of incidence is different at each point on the curved surface. Still, at each point, one measures from the perpendicular to the surface at that point, just as described above. Some more technical stuff. We may say a beam has zero width if the width of the beam is very much smaller than the radius of curvature of the surface measured at the place where it strikes the surface. Under any circumstances, the beam reflected from a curved surface will spread, i.e. be dispersed at a range of angles relative to the incoming beam and that range depends on the radius of curvature of the reflecting surface. As mentioned above, this is small if the beam is narrow, but if you are observing reflection far enough from the reflecting surface, one can observe the spread. All this assumes "ray optics" where the sizes of the beam diameter and the radius of curvature are large compared to the wavelength of the light. It all gets more complicated otherwise.
Does a plane mirror converge a parallel beam of light?
No, a plane mirror does not converge a parallel beam of light. It reflects light rays without changing their direction, so the reflected beam remains parallel to the incident beam.
What happens to light waves during reflection?
During reflection, light waves bounce off a surface without being absorbed. They obey the law of reflection, which states that the angle of incidence is equal to the angle of reflection. This process allows us to see objects by bouncing light waves off them and into our eyes.
