Answer:
Explanation:
Given
Original Frequency
apparent Frequency
There is change in frequency whenever source move relative to the observer.
From Doppler effect we can write as
where
apparent frequency
v=velocity of sound in the given media
velocity of source
velocity of observer
here
i.e.fork acquired a velocity of
distance traveled by fork is given by
where v=final velocity
u=initial velocity
a=acceleration
s=displacement
Answer:
B. The distance between the slits and the screen is halved.
C. The slit width is doubled.
D. A green, rather than red, light source is used.
E. The experiment is conducted in a water-filled tank.
Explanation:
As we know that the position of first minimum is given as
so we have
so width of minimum is given as
now if we need to decrease the angular position of minimum
1). so we can decrease the distance of screen from the slit
2). we can decrease the wavelength
3). We can increase the width of the slit
So correct answer will be
B. The distance between the slits and the screen is halved.
C. The slit width is doubled.
D. A green, rather than red, light source is used.
E. The experiment is conducted in a water-filled tank.
