Calculate the frequency of red light of wavelength - Physics Forums
网页2008年5月11日 · To convert wavelength to frequency for red light, you can use the formula frequency = 3.00 x 10^8 meters per second / wavelength in meters. The frequency of red light with a wavelength of 700 nanometers is approximately 4.29 x 10^14 hertz. The frequency of red light can affect the human eye by determining the color perception and …
What Is the frequency of red light? - Physics Forums
网页2017年5月10日 · The speed of light in a vacuum is 3.00x (10*8)m/s. Using the equation v=fx λ, calculate the frequency of red-light. (I was told to use the wavelengths given from textbook) Wavelength/λ =700nm. v=300,000,000 <-- ( I need help understanding this.
How Wide is the Central Bright Fringe in Single Slit Diffraction?
网页2013年3月27日 · Single slit diffraction Homework Statement Red light of wavelength 633nm from a helium-neon laser passes through a slit 0.390mm wide. The diffraction pattern is observed on a screen 3.00m away. Define the width of a bright fringe as the distance between the minima on either side. What is...
Wavelength of light (air vs. water) - Physics Forums
网页2005年5月25日 · The wavelength of light affects its behavior in air and water in several ways. In water, the shorter wavelength makes the light appear to bend more, resulting in objects appearing closer and larger. In air, the longer wavelength allows light to travel further, resulting in clearer visibility over longer distances. 4.
Doppler Effect -- How fast would you need to go for a red light to ...
网页2017年6月21日 · The Doppler Effect causes an apparent shift in the wavelength of light, which changes its color. When a source of light is moving towards an observer, the wavelength is compressed, making the light appear bluer. When the source is moving away, the wavelength is stretched, making the light appear redder. 3.
Question on a Double Split Problem - Physics Forums
网页2007年1月17日 · A mixture of red light (wavelength = 665 nm) and yellow-green light (wavelength = 565 nm) falls on the slits. A flat observation screen is located 2.17 m away. What is the distance on the screen between the third-order red fringe and the third-order yellow-green fringe? d= 0.153mm = 1.53 x 10^-3m red wavelength= 665 nm = 6.65 x 10 …
Velocity of red light vs. blue light in water - qualitative reasoning?
网页2011年3月31日 · 7,463. tdev said: when monochromatic light as in red and blue light go through water their frequency remains constant so,the velocity depends on wavelength only .since blue light has smaller wavelength than red its velocity is also less than that of reds. Please try not to reply to 2 1/2 year old threads. Nov 23, 2013.
Calculate Red Light Wavelength in Liquid | Angle of Refraction
网页2007年12月21日 · 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?
Determining the Index of Refraction - Physics Forums
网页2008年4月9日 · In summary, the frequency of blue light is 4.62*10^{14} Hz, the frequency of red light is 6.67*10^{14} Hz, and the index of refraction of a material in which the red-light wavelength is 450 nm is c/v.
Special Relativity Problem -- Speeding through a red light to make …
网页2010年4月14日 · Being more familiar with length in the Special Theory of Relativity, we consider the wavelength of light in this problem instead of the frequency. for red light average = 685 m = 685 nm. for green light average = 533 m = 533 nm. Red light becoming green with length contraction. = = = 0.605443.
