Calculate Refraction of Red Light Wavelength 750nm

AI Thread Summary
To calculate the wavelength of red light in a liquid, the index of refraction is determined using Snell's Law: n1sin(theta1) = n2sin(theta2). Given the angle of incidence at 39 degrees and the angle of refraction at 17 degrees, the index of refraction for the liquid can be calculated. The wavelength in the liquid can then be found using the formula n = wavelength1/wavelength2, where the wavelength in air is 750nm. The calculated wavelength of red light in the liquid is approximately 349nm. Understanding these principles is essential for accurate refraction calculations.

Red light travels from air into liquid at an angle of incidence of 39 degrees and an angle of reflection of 17 degrees. Calculate the wavelength of the red light in the liquid if it's wavelength in the air is 750nm. If someone coule tell me how to go about this question that would be very helpful, thanks.

I believe you use n1sin theta1 = n2sin theta2 to find out the index of refraction for the liquid and then use n = wavelength1/wavelength2

Dang i need to learn how to use latex.
 
Thanks for the equation, the answer I received was 349nm. I think that sounds about right.

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
