shown.When light travels from turpentine oil to water the speed of lIght_______ *​

Answer 1

When light travels from turpentine oil to water the speed of light decreases.

Explanation:

• The speed of light is maximum in a medium with a less refractive index.
• The formula is given below.
• v = c / n  
• Where c = speed of light in a vacuum its value is 3 x 10^8 m/s.
• For higher speed, the value of "n" should be less.
• v = 3 x 10^8 / 1.48
• v = 2.0 x 10^8 m/s
• Thus speed of light decrease due to high refractive index value.

Answer 2

Answer:When light travels from turpentine oil to water the speed of light decreases.

Explanation:

1. The speed of light is maximum in a medium with a less refractive index.
2. The formula is given below.
3. v = c / n  
4. Where c = speed of light in a vacuum its value is 3 x 10^8 m/s.
5. For higher speed, the value of "n" should be less.
6. v = 3 x 10^8 / 1.48
7. v = 2.0 x 10^8 m/s
8. Thus speed of light decrease due to high refractive index value.
