Aphysics professor wants to perform a lecture demonstration of young's double-slit experiment for her class using the 633-nm light from a he-ne laser. because the lecture hall is very large, the interference pattern will be projected on a wall that is 7.0 m from the slits. for easy viewing by all students in the class, the professor wants the distance between the m=0 and m=1 maxima to be 35 cm. what slit separation is required in order to produce the desired interference pattern?

when earth is in rotational motion around the sun,it displaces from its place.

when a ball is placed on an inclined surface it does both the rotational and circular motion.

explanation:

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
