a mercury lamp emits radiation with a frequency of 6.83 x 1014 hz. what is the wavelength of this radiation?

fill in the blanks as you answer the question. remember to include units. (if you need to write a superscript, put a ^ before the number to be superscripted. for example, x2 would be written as x^2.)

step 2: what is the speed of light to four significant figures?

step 3: what is the frequency of the light from the mercury lamp?

step 4: what is the wavelength of the light from the mercury lamp? blank space 3

Wavelength of this beam of light: .

Explanation:

The speed of light in vacuum is approximately .

Light behaves like a wave. The wavelength of a wave is equal to the distance that it travels (in the given medium) in each period of oscillation.

On the other hand, the frequency of a wave is the number of periods in unit time. means one oscillation per second. The frequency of this particular wave is . In other words, there are oscillations in each second.

The period of oscillation will be equal to

.

In that period of time, a beam of light in vacuum would have traveled  

.

In other words, if this beam of light of frequency is in vacuum, its wavelength will be equal to .

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
