Answer:
A. decrease the slit separation
Explanation:
Double slit experiment was done to study the phenomenon of interference of light. It gives a definitive proof of wave nature of light.
In the double slit experiment
the distance between the fringes in the interference pattern is given by
D= distance between the slit and the screen
d= distance between the slits
λ= wavelength
therefore, and increase in Δy may decrease d that is
:A. decrease the slit separation
Answer:
The third choice:
Explanation:
The cork is positively charged, therefore we know tat there must be excess of positively charged protons present.
The charge of a proton is
;
therefore, the number that makes up a charge of is
which is the 3rd choice.
The formula to use is
t is time. v is velocity. d is distance
t= 4 seconds
the answer is C
No, force = mass x acceleration, so an object moving at a faster speed due to this!
