Answer:
The wavelength of incident light is
Explanation:
The physicist Thomas Young established, through his double slit experiment, a relation between the interference (constructive or destructive) of a wave, the separation between the slits, the distance between the two slits to the screen and the wavelength.
(1)
Where is the distance between two adjacent maxima, L is the distance of the screen from the slits, is the wavelength and d is the separation between the slits.
The values for this particular case are:
Then, can be isolated from equation 1
(2)
However, before equation 2 can be used, it is necessary to express and d in units of meters.
⇒
⇒
Finally, equation 2 can be used.
Hence, the wavelength of incident light is
I think it’s a. the lithosphere
PART A)
Heat released by iron = heat gain by water
now we have
PART B)
When endothermic changes takes place in the system then system absorbs the energy from its surrounding and keeps on cooling down
Due to this the observer will feel the cool down of the surface temperature and conclude that it is an endothermic reaction
PART C)
When a substance freezes its temperature do not change but if we will check the potential energy of molecules we can conclude that the system released its energy which is known as latent heat.
This will lead to the increase in its potential energy
And due to this decrease in latent heat the substance will freeze
A prominence is a loop of cool incandescent gas that extends above the photosphere. A solar flare is an explosive release of energy that comes from the sun and causes magnetic ditrubances.
C = Q/V, and since C is a constant, if voltage is doubled, charged will be doubled as well. Therefore charge will be 2Q
