Question

determine the speed of light in fused quartz if fused quartz has an index of refraction of 1.46

Answer 1

Answer:

Hey mate here is your answer,

The answer is 4.86 *10^-8

Explanation:

It is so as we know that:-

Refractive index= Speed of light in air/Speed of light in that medium

Therefore,

1.46=3*10^-8/Speed of light in fused quartz

1.46/3*10^-8=Speed of light in fused quartz.

Therefore it is 4.86 *10 ^-8

I hope that this will help you.

Answer 2

Concept introduction:

The speed of light in vacuum, typically abbreviated as c, is an important scientific constant in many fields of physics. Its actual speed is 299792458 metres per second (about 300000 kilometres per hour or 186000 miles per hour).

Given:

Here it is given that the refraction index is $1.46$.

To find:

We have to find the the speed of light in fused quartz.

Solution:

Refractive index= Speed of light in air/Speed of light in that medium

So,

$1.46=\frac{3*10^{8} }{Speedof light in that medium} \\- > Speed of light in that medium=\frac{3*10^{8}}{1.46} \\- > Speed of light in that medium=2.05*10^8m/s$

Final answer:

So, the final answer of the question is -$2.05*10^8m/s$.
