WILL FAN AND MEDAL
The wavelength of a specific photon in the infrared spectrum is
4 × 10^6 meters. Given that the speed of light is 2.998 × 10^8 m/s, what would be the frequency of this infrared wave?
11.992*10^2 Hz
0.7495*10^14 Hz
11.992 * 10^2 Hz
0.7495 * 10^14 Hz

Best ResponseYou've already chosen the best response.1speed of light = wavelength x frequency frequency = speed of light/ wavelength do the math!!

Best ResponseYou've already chosen the best response.1@whateven we need to understand the units first, I agree with what @Cuanchi said

Best ResponseYou've already chosen the best response.1speed of light is m/s and the wavelength is in meters.

Best ResponseYou've already chosen the best response.1let's take @Cuanchi's formula \[\frac{ speed of light }{ wavelength } = \frac{ m/s }{ m } = \frac{ 1}{ s } = frequency\] all you need to do is plug in the numbers.

Best ResponseYou've already chosen the best response.0I don't know where to plug them in and get a result that matches my choices that's the problem

Best ResponseYou've already chosen the best response.1The units are wavelength = meters speed of light = meters/ seconds frequency = 1/seconds you dont need to do any conversion of units, just apply the formula that correlate the speed of light with the wavelength and the frequency

Best ResponseYou've already chosen the best response.0This still isn't helping. I plug it in like you say and my calculator says syntax error ?

Best ResponseYou've already chosen the best response.1@whateven use ( ) around the numbers like this \[\frac{ (2.99x10^{8}) m/s }{ (4.0x10^{6})m }= Hz \]

Best ResponseYou've already chosen the best response.07.495*10^13 so something is wrong @photon336

Best ResponseYou've already chosen the best response.1but in the answers they wrote it strangely, if you moved the decimal place in the 7.4 1 over to the right what answer choice would you get?
