he index of refraction of crown glass is 1.53 for violet light, and it is 1.51 for red light.

(a) What is the speed of violet light in crown glass?
(b) What is the speed of red light in crown glass?

Please help, I have tried everything and nothing is working

(a) c / 1.53

(b) c / 1.51

c is the speed of light ... 3.00E8 m/s

Omg Thanks!!

To find the speed of light in crown glass, we can use the formula:

Speed of light in a medium = Speed of light in vacuum / Index of refraction

(a) To find the speed of violet light in crown glass, we'll use the index of refraction for violet light, which is 1.53.

Speed of violet light in crown glass = Speed of light in vacuum / Index of refraction for violet light

Since we know the speed of light in a vacuum is approximately 3.00 x 10^8 meters per second (m/s):

Speed of violet light in crown glass = (3.00 x 10^8 m/s) / 1.53 = 1.96 x 10^8 m/s

Therefore, the speed of violet light in crown glass is approximately 1.96 x 10^8 meters per second (m/s).

(b) To find the speed of red light in crown glass, we'll use the index of refraction for red light, which is 1.51.

Speed of red light in crown glass = Speed of light in vacuum / Index of refraction for red light

Using the same value for the speed of light in a vacuum:

Speed of red light in crown glass = (3.00 x 10^8 m/s) / 1.51 = 1.99 x 10^8 m/s

Therefore, the speed of red light in crown glass is approximately 1.99 x 10^8 meters per second (m/s).

To solve this problem, we need to use Snell's Law, which relates the index of refraction and the speed of light in different media.

(a) To find the speed of violet light in crown glass, we first need to determine the ratio of speeds between the two mediums. We can calculate this using the equation:

Speed of light in a medium = Speed of light in vacuum / Index of refraction

The speed of light in a vacuum is approximately 3.00 x 10^8 meters per second (m/s), denoted as c.

Therefore, the speed of violet light in crown glass is:

Speed of violet light in crown glass = c / Index of refraction for violet light

= (3.00 x 10^8 m/s) / 1.53

= 1.96 x 10^8 m/s

So, the speed of violet light in crown glass is approximately 1.96 x 10^8 meters per second (m/s).

(b) Similarly, to find the speed of red light in crown glass, we use the same approach:

Speed of red light in crown glass = c / Index of refraction for red light

= (3.00 x 10^8 m/s) / 1.51

= 1.99 x 10^8 m/s

Hence, the speed of red light in crown glass is approximately 1.99 x 10^8 meters per second (m/s).
