Answer:
The color of the central maximum is white.
Explanation:
A diffraction grating in optics is generally known as an optical component that contains a periodic structure. It is commonly used to breakdown and diffract light into different beams that move in several directions. For example, if a light ray is allowed to pass through the component (i.e. diffraction grating), the central maximum will have a white color.
False, Because there is some cases where enlarged image needed.
Answer:
20 m/s
Explanation:
First, you have to convert kilometers (72) to meters (72.000) then do the same with hours (1 hour) and seconds (3.600) Divide this numbers and you will get a result.
Explanation:
It is given that,
Speed of the electron in horizontal region, 
Vertical force, 
Vertical acceleration, 
..........(1)
Let t is the time taken by the electron, such that,
...........(2)
Let 
is the vertical distance deflected during this time. It can be calculated using second equation of motion:
u = 0
So, the vertical distance the electron is deflected during the time is 0.426 mm. Hence, this is the required solution.
