Answer 1

Answer:

Q.The speed of light in q transparent medium is 0.6 times that of its speed in vacuum. The refractive index of the medium is:

(a) 1.66

(b) 1.96

(c) 1.26

(d) 1.29

$\textbf{Answer:-}$ option a) 1.66

The speed of light in a transparent medium is 0.6 times that of its speed in vacuum. The speed of light in vacuum, commonly denoted c, with c = f

where c is the the speed of light.

Therefore,

Refractive index of medium = $\dfrac{speed~of ~light~in~vacuum}{speed ~of~ light~ in~ medium}$

RI = $\frac{1}{0.6}$ = $\frac{5}{3}$ or 1.66

• Thus, the speed of light in a transparent medium is 0.6 times that of its speed in vacuum which will be 1.66.

Answer 2

Answer:

A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations automatically. Modern computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks
