An Incident ray traveling in a slower medium strikes a boundary with a faster medium. What happens when its angle of Incidence is greater than the critical angle?
OA.
The refracted ray makes an angle of 90°.
OB.
There is total internal reflection in the faster medium.
OC.
There is total internal reflection in the slower medium.
OD
The reflected ray makes an angle of 90°
OE. The reflected ray makes an angle equal to the critical angle.

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
