Suppose a diffraction grating has three slits. (a) If the bottom slit contributes to the zeroth-order maximum, what is the difference between the distances traveled by light from the middle and bottom slits?
(b) What is the difference between the distance traveled by the light from these two slits at the dark mode surrounding the zeroth-order maximum?​

divide the right side by the left side

0.024÷1.2=0.02 for example

seeing the graph would

this could be newton#'s law of cooling. the cooling curve is exponential

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
