explain partial reflection,critical angle and total internal reflection with the help of neat labelled diagram .
plz give me a answer 20 points
Answers
Answer:
critical angle is defined as the incident angle in denser medium for which the refracted angle is 90 degrees in the rarer medium.
the total internal reflection takes place when the incident angle in denser medium is more than the critical angle.
Answer:
Total internal reflection, in physics, complete reflection of a ray of light within a medium such as water or glass from the surrounding surfaces back into the medium. The phenomenon occurs if the angle of incidence is greater than a certain limiting angle, called the critical angle.
Total internal reflection takes place when the angle of incidence for the light ray is greater than the so-called critical angle. The critical angle is defined as the angle of incidence that provides an angle of refraction of 90-degrees.
