Solving for Frequency & Wavelength of Light in Air & Glass

AI Thread Summary
To solve for the frequency and wavelength of red light transitioning from air to glass, the speed of light in a vacuum (c = 3 x 10^8 m/s) is essential. The frequency of light can be calculated using the formula f = c/λ, where λ is the wavelength in air. When red light with a wavelength of 560 nm enters glass, its velocity changes to 1.96 x 10^8 m/s, which can be used to find the new wavelength in glass using the formula λ = v/f. Refraction concepts are crucial for understanding how light behaves in different media, and the refractive index can be applied to determine the velocity of light in glass. The discussion emphasizes the importance of these formulas and concepts in solving light-related problems.

Problem: red light of wavelength 560nm is passed from air into glass where its velocity is 1.96 x 10^8 m/s.
(c=3*10^8)
Find the frequency of the light in air and the wavelength of the light in glass.

Can someone please tell me what c is and what formulas i need to use.
thanks

c is the symbol for the speed of light in a vacuum.

Have you met the concept of refraction?
 
Is this how u could calculate the velocity?
n=vair/vglass
vglass=vair/n
(3x10^8/1.52) = 197368421.1 m/s
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
