WebThe velocity of blue light is 300,000,000 m/sec, and its frequency is 650,000,000,000,000 cycles per second. What is the wavelength of blue light? Use scientific notation to make your calculation and express your answer. (round to the hundredths places) The wavelength of light is given by the velocity divided by the frequency. WebNov 25, 2013 · 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 …
WebMar 10, 2024 · It's also no more damaging than blue light from the sun, Dr. Khurana says. Too much exposure to ultraviolet light from the sun increases the risks of eye diseases, including cataracts, growths on the eye and cancer. We know less about blue light. Its effects are still being researched. Some studies suggest that not enough exposure to … In classical physics, light is described as a type of electromagnetic wave. The classical behaviour of the electromagnetic field is described by Maxwell's equations, which predict that the speed c with which electromagnetic waves (such as light) propagate in vacuum is related to the distributed capacitance and inductance of vacuum, otherwise respectively known as the electric constant ε0 and the magnetic constant μ0, by the equation
WebBlue light has shorter wavelengths and higher energy than other colors. Some research shows a link between eye damage and short-wave blue light with wavelengths between … WebJan 14, 2024 · When an object is moving away from us, the light from the object is known as redshift, and when an object is moving towards us, the light from the object is known as blueshift.
