An optical engineer needs to ensure that the bright fringes from a double-slit are 15.7 mm apart on a detector that is 1.12 m from the slits. If the slits are illuminated with 633 nm light, how far apart must the slits be?
An 8-m-long beam, weighing 14,700 N, is hinged to a wall and supported by a light rope that is attached 2.0 m from the free end of the beam. calculate the reaction force of the wall on the beam
As a bacterium swims through water it propels itself with its flagella so as to overcome the frictional drag forces and move at, more or less, constant velocity of 100 micrometers/s for periods of time. If the frictional drag force on a bacterium is ..
A double slit experiment is performed with sodium(yellow) light of wavelength 589.3nm and the interference pattern is observed on a screen 100 cm away. determine the separation between slits
Refrigerant-134a enters a compressor at 180 kPa as a saturated vapour with a flow rate of 0.35 m3/min and leaves at 700 kPa. The power supplied to the refrigerant during compression process is 2.35 kW. What is the temperature R-134a at the exit of th..
