In the hydrogen atom, the energy spacing between the is 4.07 x 101 j (joules). when an is the frequency of the photons emitted? electron falls from the fourth to the second orbital, what from the a. 3.04 x 10 hz (or cycles per second) b. 608 x 1014 ã c. 3.04 x 1015 hz d. 4.00 x 10'"hz e. 4.00 x 10 hz

The frequency of the photon is .

Explanation:

Given that,

Energy

We need to calculate the energy

Using relation of energy

Where, =  energy spacing

Put the value of h into the formula

Hence, The frequency of the photon is .

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
