Answer:
Explanation:
The relationship between angle and wavelength for maxima and minima in Young's double slit experiment is given by
For constructive interference
![d\sin \theta =m\lambda](https://tex.z-dn.net/?f=d%5Csin%20%5Ctheta%20%3Dm%5Clambda%20)
For Destructive interference
![d\sin \theta =(m+\frac{1}{2})\lambda](https://tex.z-dn.net/?f=d%5Csin%20%5Ctheta%20%3D%28m%2B%5Cfrac%7B1%7D%7B2%7D%29%5Clambda%20)
where ![\lambda =wavelength](https://tex.z-dn.net/?f=%5Clambda%20%3Dwavelength)
![d=slit\ width](https://tex.z-dn.net/?f=d%3Dslit%5C%20width)
m=order of maxima and minima
for second order maxima i.e. ![m=2](https://tex.z-dn.net/?f=m%3D2)
For smallest separation taking ![\lambda =400 nm, \theta =90^{\circ}](https://tex.z-dn.net/?f=%5Clambda%20%3D400%20nm%2C%20%5Ctheta%20%3D90%5E%7B%5Ccirc%7D%20)
![d\sin 90=2\times 400\times 10^{-9}](https://tex.z-dn.net/?f=d%5Csin%2090%3D2%5Ctimes%20400%5Ctimes%2010%5E%7B-9%7D)
![d=0.8\times 10^{-6}](https://tex.z-dn.net/?f=d%3D0.8%5Ctimes%2010%5E%7B-6%7D)
![d=0.8\mu m](https://tex.z-dn.net/?f=d%3D0.8%5Cmu%20m)
Answer:
c. Light energy to thermal energy
Explanation:
The energy from the sun comes in the form of light energy but is converted to thermal energy.
<u>The Weight </u>is a vector whose magnitude is the product of the mass m of the object and the magnitude of the local gravitational acceleration. Its always directed toward the center of the Earth.
