When light passes from one medium to another, part of it continues on
into the new medium, while the rest of it bounces away from the boundary,
back into the first medium.
The part of the light that continues on into the new medium is <em>transmitted</em>
light. Its forward progress at any point in its journey is <em>transmission</em>.
Its direction usually changes as it crosses the boundary. The bending is <em>
refraction</em>.
The part of the light that bounces away from the boundary and heads back
into the first medium is <em>reflected</em> light. The process of bouncing is <em>reflection</em>.
600km since it would be 1350 divided by 2.25
Answer:
The value of the angle is ![\bf{ \sin^{-1}[h/am_{e}v]}](https://tex.z-dn.net/?f=%5Cbf%7B%20%5Csin%5E%7B-1%7D%5Bh%2Fam_%7Be%7Dv%5D%7D)
.
Explanation:
Given:
The condition for diffraction minima is
where, 
is the slit-width, 
is the angle of incidence, 
is the order number and 
is the wavelength of the light.
The wavelength of an electron traveling through a medium is governed by de Broglie's hypothesis.
According to de Broglie's hypothesis
Here, 
is Planck's constant, 
is the mass of the electron and 
is the velocity of the electron.
For first minimum 
.
From equation (1), we have
![&& a \sin \theta = \dfrac{h}{m_{e}v}\\&or,& \theta = \sin^{-1}[\dfrac{h}{am_{e}v}]](https://tex.z-dn.net/?f=%26%26%20a%20%5Csin%20%5Ctheta%20%3D%20%5Cdfrac%7Bh%7D%7Bm_%7Be%7Dv%7D%5C%5C%26or%2C%26%20%5Ctheta%20%3D%20%5Csin%5E%7B-1%7D%5B%5Cdfrac%7Bh%7D%7Bam_%7Be%7Dv%7D%5D)

Answer:
Yes.
Explanation:
Yes, we emphasize performance over participation of kids in a competition which causes negative effect on kid's personality. We also prefer those children whose families can afford the fees which is our big failure. We should emphasize participation over performance and prefer those child who has the ability to win the game instead of those who can afford the fees.
