Want this question answered?
Use the formula: speed = frequency x wavelength.
75mm in to m
well is the 75 million
Speed (of a wave) = frequency x wavelengthTherefore, you have to: * Convert the wavelength to meters. * Divide the speed of light - which is 300 million meters/second - by this wavelength. The answer will be in Hz.
Red light has a longer wavelength than blue light, (i.e. greater distance for one oscillation of red light compared to blue light) so there are less oscillations in the same period of time for red light, and thus red light has a lower frequency than blue light. More concisely: Wavelength = Wavespeed / Frequency , where wavespeed is constant So Frequency = Wavespeed / Wavelength Therefore as wavelength increases, frequency decreases. Make sense? Jack

Mix it with a local oscillator whose frequency is (the IF frequency) away from the frequency of the FM signal you're interested in.
The answer is in the question! 5 Hz Also, a wavelength cannot be 5 cycles - wrong units.
You need specify the units associated with the number 10.In any event, a very simple relationship exists between the wavelength and the frequency for all forms of electromagnetic radiation - the product of the two is equal to the speed of light. Therefore, the frequency you want to know can be determined by dividing the speed of light by the wavelength. Just be sure that you are consistent with the units
The formula to find the frequency is f = c/lambda c - the speed of light which equals to 3 x 108 m s-1 lambda = 400 nm. nano has mathematical notation 10-9m Hence required frequency f = 3 x 108 / 400 x 10-9 f = 7.5 x 10 14 Hz.
