Answer:
(3) TIR causes a portion of the light to be refracted and the rest to be reflected
Explanation:
Total internal reflection is the reflection of a light ray completely within a medium for example glass or water which bounces back after reflecting from the surrounding surfaces into the medium. When the incident angle is more than an certain limiting angle, called the critical angle, the phenomenon is called total internal reflection.
In total internal reflection none of the portion of the incident light gets refracted, it gets only reflected multiple times within the medium.
Hence the false statement is (3).
Answer:
d. Photoreceptors, such as rods and cones
Explanation:
The retina in the eye , is referred to as the screen where the image of the object is made .
If the image of the object falls on the retina , ethen only a person can seen the object .
The retina consists of some specialized cells , i.e. , the photoreceptors like the cones and rods , which are responsible for the conversion of the light into the electrical signal , which then are carried to the brain , via neurons ,and the person sees the object.
