The sine of the incident angle is 0.217; the sine of the refracted angle is 0.173. Calculate the index of refraction. n =

1.3.

Explanation:

From the question given above, the following data were obtained:

Sine of incident angle (Sine i) = 0.217

Sine of refracted angle (Sine r) = 0.173

Refractive index (n) =?

From snell's law, the Refractive index is simply defined as the ratio of the sine of the incident angle to sine of the refracted angle. Mathematically, it is expressed as:

Refractive index = Sine of incident angle / sine of refracted angle

n = Sine i / Sine r

With the above formula, we can obtain index of refraction as shown below:

Sine of incident angle (Sine i) = 0.217

Sine of refracted angle (Sine r) = 0.173

Refractive index (n) =?

n = Sine i / Sine r

n = 0.217 / 0.173

n = 1.3

Thus, the index of refraction is 1.3.

3. when u click on your profile pic, there appears four options on the top.

4. click on the 1st option and scroll down and go at the bottom.

5. click on edit profile.

6. there appears a option 'prefernces' and at that option at the right side , 'edit' is written.

7. click on the edit option.

8. there is a option " i want to delete my account" and click on that.

hope this u

and ur welcm
