Question 14 options:

crown glass (n=1.52)


flint glass (n=1.66)


glycerol (n=1.47)


water (n=1.33)

Answer 1

Answer:

The Answer to question 14 is : glycerol (n=1.47)

Answer 2

The material should be considered as the glycerol (n=1.47).

Calculation of the material:

Since

a beam of monochromatic light (f=5.09 × 10^14 Hz) has a speed of 2.04× 10^8 meters per second.

Now the material should be

= 3*10^8 / 2.04× 10^8

= 1.47

Hence, The material should be considered as the glycerol (n=1.47).
