The aluminum foil would reflect the most light !
Answer:
Mono-chromatic, Poly-chromatic. When a wave moves from one medium into another at an angle other than 90 degrees the wave will change direction and continue to follow a new straight-line path

Answer:
Electric field, E = 40608.75 N/C
Explanation:
It is given that,
Mass of electrons,
Initial speed of electron, u = 0
Final speed of electrons,
Distance traveled, s = 6.3 cm = 0.063 m
Firstly, we will find the acceleration of the electron using third equation of motion as :
Now we will find the electric field required in the tube as :
E = 40608.75 N/C
So, the electric field required in the tube is 40608.75 N/C. Hence, this is the required solution.
<span>The speed of water in pipe is given by:
V=0.408(Q/D^2)
V=speed
Q=flow rate
D=diameter of pipe
Hence, the speed of the water is inversely proportional to square of diameter
If the speed of water through 1-cm diameter is V
Then, speed of water through 0.5 cm diameter is
=V/[(1/2)^2)]
=V/(1/4)
=4V
Hence, compared to the speed of water in 1 cm pipe, the speed in the 1/2 cm pipe is four times.</span>
