Calculate Red Light Wavelength in Liquid | Angle of Refraction

In summary, the conversation discusses the relationship between the angle of incidence and reflection for red light traveling from air into liquid. The wavelength of the red light in the liquid is calculated to be 750 nm, with no change in frequency. Additional information is provided regarding the importance of using descriptive titles when posting for practicality and ease of navigation.

Red light travels from air into liquid at an angle of incidence of 390 and an angle of reflection of 170. Calculate the wavelength of the red light in the liquid if its wavelength in air is 750 nm

can you give me some hint for this one too? :cry:

The frequency does not change. Is this hint good enough?

double post...

Is it? I think the OP had posted another post with the title "another...", but the topic was different.

Dear rhxoehwhfh,

Please sacrifice originality for practicality and try to give your posts names dealing with the subject, for everybody's benefit.

1. What is the formula for calculating red light wavelength in a liquid?

The formula for calculating red light wavelength in a liquid is λ = λ₀ / n, where λ is the wavelength in the liquid, λ₀ is the wavelength in vacuum, and n is the refractive index of the liquid.

2. How do I determine the angle of refraction for red light in a liquid?

To determine the angle of refraction for red light in a liquid, you can use the formula sin θ = (n₀ / n) * sin θ₀, where θ is the angle of refraction, n₀ is the refractive index of the medium the light is coming from, and n is the refractive index of the liquid.

3. What is the refractive index of a liquid and how is it related to red light wavelength?

The refractive index of a liquid is a measure of how much the speed of light is reduced when passing through the liquid. It is related to red light wavelength because the wavelength of light decreases as it passes through a medium with a higher refractive index.

4. Can I use the same formula to calculate the wavelength and angle of refraction for other colors of light?

Yes, you can use the same formula to calculate the wavelength and angle of refraction for other colors of light, but you will need to know the specific refractive index for that color in the given liquid.

5. How does the angle of incidence affect the angle of refraction for red light in a liquid?

The angle of incidence does not affect the angle of refraction for red light in a liquid. The angle of refraction is solely determined by the refractive indices of the two mediums involved and the angle of incidence.
