Pluto is a dwarf planet that's why
highest energy level to the ground state.
Explanation:
The transition from the highest energy level to the ground state.
An electron has a discrete amount of energy accrued to it in any energy level it belongs to.
Electrons can transition between one energy level or the other.
- When electrons change state, they either release or absorb energy.
- When an atom absorbs energy, they move from their ground to final state which is consistent with the energy of the final state.
- When electrons release energy, they move from excited state to their ground state.
- Electrons will release the greatest amount of energy when they move from the highest energy level to the ground state.

Answer:
A
Explanation:
to simplify let's make it apart the denominator into three part
![\frac{ {3xy}^{2} }{ {x}^{2} {y}^{2} } - \frac{ {8x}^{2} y}{ {x}^{2} {y}^{2} } + \frac{ {5x}^{2} {y}^{2} }{ {x}^{2} {y}^{2} }](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%7B3xy%7D%5E%7B2%7D%20%7D%7B%20%7Bx%7D%5E%7B2%7D%20%20%7By%7D%5E%7B2%7D%20%7D%20%20-%20%20%5Cfrac%7B%20%7B8x%7D%5E%7B2%7D%20y%7D%7B%20%7Bx%7D%5E%7B2%7D%20%7By%7D%5E%7B2%7D%20%20%7D%20%20%2B%20%20%5Cfrac%7B%20%7B5x%7D%5E%7B2%7D%20%20%7By%7D%5E%7B2%7D%20%7D%7B%20%7Bx%7D%5E%7B2%7D%20%20%7By%7D%5E%7B2%7D%20%7D%20)
now let's simplify
![\frac{3}{x} - \frac{8}{y} + 5](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7Bx%7D%20%20-%20%20%5Cfrac%7B8%7D%7By%7D%20%20%2B%205)
so the answer is A

Answer: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays
Explanation:
The equation of grating is given by :
![(a+b)\ sin\theta=n\lambda](https://tex.z-dn.net/?f=%28a%2Bb%29%5C%20sin%5Ctheta%3Dn%5Clambda)
Here,
(a+b) is called grating element
N is the number of slits per unit length, ![N=\dfrac{1}{(a+b)}](https://tex.z-dn.net/?f=N%3D%5Cdfrac%7B1%7D%7B%28a%2Bb%29%7D)
n is the order
is the wavelength of light used
is the diffraction angle
Here, we need to write the effect on the interference pattern produced by a grating if the number of slits per unit length is increased. If the number of slits per unit length increases, the grating element decreases such that the angle of diffraction increases. Hence, the interference pattern shrinks.
