Question

Use the graph below to answer the following question:

Graph titled maximum kinetic energy of ejected photo electron versus incoming frequency is shown. The y axis is labeled maximum kinetic energy and scales from negative 3 to positive 3 electron volts. The x axis is labeled frequency from 0 to 11 times 10 to the 14 hertz. A line connects the points 0, negative 2 and 2.5, negative 1 and 5, 0 and 8, 1 and 10, 2.

If you use a different experimental photo-missive material, what would be the same on the graph?

The y-intercept
The x-intercept
The slope
The maximum kinetic energy of the photoelectron

Answer 1

Answer:

C. the slope

Explanation:

I've been doing the course on FLVS and they state clearly that,

"The slope is the physical constant Planck’s constant. This means the slope of the graph will be numerically the same as the x-intercept and y-intercept change."

Hope this helps

Answer 2

From the options when a different experimental photo-missive material is used what will remain the same on the graph is the SLOPE

Given that slope is a physical constant Therefore the slope of the graph will remain the same ( i.e. numerically ) even if  labels of the x-intercept and y-intercept change. The x intercept and y-intercept labels will change also the maximum kinetic energy of the photoelectron will change due to the change in photo-missive material

Hence we can conclude that when a different photo-missive material is used the slope, of the graph ( numerical value ) on the graph will still remain the same.
