Use MATLAB to generate the 256x256 black image (0 values) with the 1-valued central block (white square) of 64x64 size.
The two plane mirrors forms an angle of 21 degrees. A light ray enters the system and is reflected once off each mirror. Via what angle is the ray turned?
Suppose that the light of wavelength 490 nm is being viewed. As well, suppose that diffraction effects, instead of atmospheric turbulence, limit the resolving power of the telescope.
A non-reflective coating having n = 1.38 covers the glass having n = 1.52 of a camera lens. Supposing that the coating prevents reflection of a specific wavelength (that is, wavelength (591nm)) find
Determine the efficiency of a machine which is driven by a falling wt of 25,000N for 10m when you get 125,000J out of the machine.
In how many different ways can we pair up all members of club? Write 3 different ways of counting this, describing each method.
Determine the magnitude of the water velocity at this point when the volume flow rate is 0.600 m^3/s ? (ii) At a second point in the pipe the water velocity consists of a magnitude of around 15.0 m/
A circular hole of 1.10 cm in diameter is cut in the side of a big water tank, 25.0 m beneath the water level in the tank. The top is open to the air. Compute (i) the speed of efflux; (ii) the volum
A tall object of around 4.5 cm is positioned 26 cm in front of the spherical mirror. You want to generate a virtual image which is upright and 3.5 cm tall. (i) What kind of mirror (concave or convex
The magnification of the object is around -3.0. Is the image on the similar side of the mirror as the object? Is the image virtual or real? Is the image upright or inverted? Is the mirror concave or

Let differential equation dy/dx=6x, with intial condition y(0)=2. Use Euler's method with 2 steps to find y when x=1: y(1)=? Now use 4 steps: y(1)=?
The threshold wavelength in the photoelectric experiment is found to be 500 nm. Determine the work function? Determine what will be the photoelectric stopping potential if 300 nm UV radiation hits t
A certain automobile engine is functioning work at the rate of around 33850 W (45 hp) with the efficiency of 26%. Determine at what rate is heat being expelled through the engine?
It has been recommended that if a concert is broadcast so that it can be seen on TV, persons viewing the concert at home (possibly miles away) might in reality listen to the sounds before a person w
A person at the beach observes that the wave crests are around 20 meters apart and that 12 waves arrive at the shore in one minute. By using this information estimate (compute) the speed of such wav
A washer (annulus) of aluminum is lying on the top of a vertical solenoid. If the current in the solenoid is all of a sudden switched on, the washer flies upward. Cautiously describe why the end of
