Answer:
For any v-t graph the acceleration is the slope of the graph. For average acceleration in a time period ‘t’ consider the change in velocity in time t and divide it by the time t. For instantaneous acceleration you need to go into the realm of differential calculus.

Explanation:
A. All living things and objects
Light ... and all other forms of electromagnetic radiation ... behaves
as if it were a stream of 'packets' that we call 'photons', each one
carrying a specific amount of energy.
Light ... and all other forms of electromagnetic radiation ... is
characterized by its wavelength. That is, once you state its wavelength,
you've stated everything there is to know about the light, including its
frequency, and the energy carried by each photon.
