    λ = ax / D λ = [ (0.9 x 10⁻³ ) * ( 3 x 10⁻³ ) ] / (5) λ = 5.4 × 10⁻⁷ m

    27) find d which is 1/n -->1/500 * 10^ (-3) = 2 x 10^-6. then d sin90=n x (600 x 10^-9) = 3 then he asked for the images so it is 3 orders for one side which is 45 degrees so for the 90 degrees it is 3 x 2= 6 + the normal ray = 7 so D 29) For a stationary wave in P there should be a node at the...

    Power = Energy / time. Power = ( 0.5 * m * v^2 ) / t Power = ( 0.5 *(rho * volume)* v^2) / t Power = ( 0.5 *(rho * area * length)* v^2) / t Power = (0.5 *(rho * area) * v^3) Power = 1300kW

    32) The arrows point downwards which means the charge at the top is positive and the bottom is negative. So, the +Q will be attracted downwards and the -Q will be attracted upwards, spinning the rod anti-clockwise. The resultant force is zero because F = E/Q and the Q (both charges) are equal...
