Explanation of Solution
Given data:
The
The refractive index of water is
Formula used:
The formula for frequency of light in a medium is as follows:
Here,
The formula for refractive index of a medium is
Here,
Explanation:
Recall the expression for frequency of light in air as a medium:
Here,
Substitute
The frequency of light is the same in any medium. However, its wavelength and velocity are different in different mediums.
Hence, the frequency of light in water is
Recall the expression for refractive index of medium:
The above expression can be re-written, if the medium is water, as
Here,
Substitute
Recall the expression for frequency of light in water as a medium:
It is written for the wavelength of light in water as
Here,
Substitute
Conclusion:
The frequency of light in air is

- The wavelength of light changes when it passes from one medium into another. Suppose green light at 550.0 nm passesfrom air into glass (n = 1.5). a. What is its wavelength in glass? b. What is its frequency? c. Do you see the same color in both media?arrow_forwardA certain kind of glass has an index of refraction of 1.650 for blue light of wavelength 430 nm and an index of 1.615 for red light of wavelength 680 nm. If a beam containing these two colors is incident at an angle of 30.00 on a piece of this glass, what is the angle between the two beams inside the glass?arrow_forwardWhich is true of diffraction? (7.6) (a) It occurs best when the slit width is less than the wavelength of a wave. (b) It depends on refraction. (c) It is caused by interference. (d) It does not occur for light.arrow_forward
