Answer:
The width of the central bright fringe becomes narrower.
Explanation:
In case of Single Slit, diffraction will occur.
Then In Single slit Diffraction, width of central fringe is
where D= distance between screen and slit
a= slit width
Thus if Screen width increases keeping other factors same then width of cental fringe becomes narrower as
The width of the central bright fringe becomes narrower.
Answer:
20 N
Explanation:
By Newton's 2nd law,
The rate of change of momentum is directly proportional to the unbalance force applied on the object,
By that you can get the equation,
F = ma
= 5 × 4 = 20 N
Chemical energy holds molecules together by forming the bonds between atoms. the form of electric bonds.
Answer:
The sun is the center of the solar system.
The planets revolve around the sun.
The formula is wavelength=speed÷frequency so if you do 15÷9 which equals 1.6
