In diffraction of light
minima occurs when
where a is width of slit and is angular deviation corresponding to minima.
for first minima m=1, and for a to be minimum, should be maximum.
maximum of is 1
so , i.e slit with should be equal to wavelength of light incident.
(b)
same concept as above in (a)
for
slit width is equal to
(c)
for
slit width should be equal to .

A science student is riding on a flat car roof train that is traveling at a constant speed of 10 mph on a straight horizontal track. The student throws a ball into the air along a path that he just made to make an initial angle of 60 degrees with the horizontal and to be in line with the track that the student's professor, who is standing nearby, observes the ball rising. How high does the ball rise vertically?

The house is losing heat to the outside air through the walls and windows at a rate of 40 MJ/J, while energy generated within the house from the people, lights and appliances amount to 6000kJ/h. For a COP of 2.4, find the power input to the heat pump
