B. Bombarded by high speed electrons.
There are already electrons with potential energy in the conductor. When it is bombarded by these high speed electrons, the potential energy is changed into kinetic energy and then the electrons are emitted from the conductor.
Hope this helps.
Velocity can be defined as Speed in a given direction
Answer:
The distance on the screen from the center of the central bright fringe to the third dark fringe is 0.831 m.
Explanation:
Given that,
Wavelength = 617 nm
Width of slit
Distance between the slit and screen L= 2.83 m
Third dark fringe m = 3
We need to calculate the distance on the screen from the center of the central bright fringe to the third dark fringe on either side
Using formula of distance
Put the value into the formula
Hence, The distance on the screen from the center of the central bright fringe to the third dark fringe is 0.831 m.
