When sound travels on a certain wave pattern or medium once it hits the surface or surfaces of another wave or mdeium and then it bounces back that is a reflected sound wave.

Electrical energy is a particle that moves through a wire and transferred into homes, work, etc to make electricity work in objects.
Explanation:
Wavelength in an emission spectrum,
The energy of an electron is given by :

Where
h is the Planck's constant
c is the speed of light
For 435 nm, the energy of the electron will be :


We know that 
So, 
So, E = 2.86 eV
The energy of the electron dropping from one energy level is 2.86 eV. We know that,

From the given energy levels :

So, the transition must be from E₅ to E₂. Hence, this is the required solution.
Under normal lighting conditions, most diamonds appear to be colorless the naked eye. Many consumers think that all diamonds are colorless, however, in reality, they come in a wide range of colors. Actualcolor differences are very subtle.
I did try to solve. I hope it is correct, below is the solution:
<span>put everything in s.i units
then the answer what u wrote is acceleration to get is divide by mass(80)
G=6.011*10^-11
M=6*10^24
R=6.4*10^6
m=80

Hope it helps.
