Arago experimentally proved bright spot.

Fresnel is credited for the solution of wave nature of light.

Explanation:

It was Poisson who showed that Fresnel's wave model of light and predicted a bright spot in the very center of a circular shadow, which he interpreted as an absurd result. But the credit to prove it experimentally goes to Arago he also gives strong evidence towards the wave theory of light,which are coherent and have a central bright spot.

Later in his honor that spot is also called Arago bright spot.

And the mathematical solution for the wave nature of light is explained by Fresnel and Huygen combined called Huygens-Fresnel principle.

So from the option we will go with Fresnel.

It was Arago who experimentally prove dthe central bright spot.

And Fresnel gives the mathematical solution of wave nature of light.

step-by-step explanation:

we are given

we have to simplify it

firstly, we will factor it

now, we can cancel like terms

now, we can combine it

so, we get

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
