Speed of the car given initially
v = 18 m/s
deceleration of the car after applying brakes will be
a = 3.35 m/s^2
Reaction time of the driver = 0.200 s
Now when he see the red light distance covered by the till he start pressing the brakes
Now after applying brakes the distance covered by the car before it stops is given by kinematics equation
here
vi = 18 m/s
vf = 0
a = - 3.35
so now we will have
So total distance after which car will stop is
So car will not stop before the intersection as it is at distance 20 m

The wavelength is
Explanation:
From the question we are told that
The distance of the slit to the screen is
The order of the fringe is m = 6
The distance between the slit is
The fringe distance is
Generally the for a dark fringe the fringe distance is mathematically represented as
=>
substituting values
=>
=>
