Given the speed of light as 3.0 108 m/s, calculate the wavelength of the electromagnetic radiation whose freq

Answer 1

velocity equals frequency times wavelength
the vel. of the radiation is = to the speed of light so if the wavelenght decreases the frequency increases
vel = freq x wavelength.

Answer 2

The relation you're able to desire to apply is: velocity = wavelength * frequency you're given v, that's the value of sunshine, and frequency, that's 7.5x10^12 Hz So now, merely resolve for wavelength: wavelength = 3x10^8 / 7.5x10^12 = 4x10^-5 m

Answer 3

Let L = vt; where L is a distance, v is velocity, and t is the time traveled. This is basic physics, now apply this to light.

Let L = vt = ct; where L is one wavelength, c is the speed of light, and t is the time it takes light to travel one wavelength. If we call one wavelength a cycle, then L = 1 cycle without loss of meaning.

In which case t = seconds to travel one cycle or seconds/cycle. Then f = 1/t = cycles/second which, ta da, is frequency by definition.

OK then L = ct = c/f; so that whatever your frequency is, simply divide it into your light speed and that gives you the length (in meters if c is in meters/sec and f is is cycles/sec) of the wave. QED.

Answer 4

_______________________________________________________

the speed of light = c = 3.0 10^8 m/s,

frequency of radiation = f

the wavelength of the electromagnetic radiation =velocity/frequency=3.0*10^8 / f

the wavelength of the electromagnetic radiation =3.0*10^8 / f
