Answer:
It will decrease
Explanation:
The double-slit interference equation, which gives us the position y of a maximum on the screen (measured relative to the central position), is
where
n is the order of the maximum
D is the distance between the slits and the screen
is the wavelength of the light
d is the separation between the two slits
From the formula, we see that y is inversely proportional to d: this means that if the separation between the slits is increased, the distance of each maximum from the central position (y) decreases, therefore the distance between the interference fringes will decrease.
Answer:
the transmission axis of polarizing sheet makes an angle of with the horizontal
Explanation:
We have given that intensity of light incident on the sheet
Average intensity of light emerging from a polarizing sheet
We have to find the angle between transmission axis with the horizontal
Intensity of light polarizing from sheet is equal to
So
So the transmission axis of polarizing sheet makes an angle of with the horizontal
