The answer to this question is true
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:
Newton's third law, if i'm not mistaken.
Explanation:
Any action that occurs will have a opposite and equal action. The greater the force u apply to the wall, the greater the force the wall exerts back at you, hence why ur hands become red if u try pushing extremely hard on the wall.
Answer:
its the ultraviolet lights
At standard atmospheric pressure, 100° C
is defined as the boiling point of water.
