Answer:
Surface charge density will be
Explanation:
We have given speed of the belt v = 43 m/sec
Width of the belt w = 61 cm
We know that charge is equal to Q = It, here Is current and t is time
And time is equal to , here L is distance and v is speed
Putting the value of t in charge equation
Surface charge density is equal to
We know that width is equal to
So
Answer:
123.18 nm
Explanation:
Given:
- Refractive index of the glass=1.5
- Index of magnesium fluoride=1.38
- Wavelength of the light =680 nm
Let t be the thickness of the film. The relation between the wavelength of light in film and thickness of the film in order to have no reflection is given by
Now According to question we have
where n is the refractive index of the film.
Now thickness t is given by
Hence the thickness of the film is calculated in order to have no reflection.
