Answer:
The magnitude of the electric field at distance r from the point charge q is 
Explanation:
Suppose, Find E(r), the magnitude of the electric field at distance r from the point charge q.
We know that,
The electric field is proportional to the point charge and inversely proportional to the square of the distance from the charge point .
In mathematically,
Where, q = charge point
R = distance from charge point
Hence, The magnitude of the electric field at distance r from the point charge q is
Answer:
y and length is directly relation
Explanation:
Given data
A single-slit diffraction pattern is formed on a distant scree
angles involved = small
to find out
what factor will the width of the central bright spot on the screen change
solution
we know that for single slit screen formula is
mass ƛ /area = sin θ and y/L = sinθ
so we can say mass ƛ /area = y/L
and y = mass length ƛ / area .................1
in equation 1 here we can see y and length is directly relation so we can say from equation 1 that the width of the central bright spot on the screen change if the distance from the slit to the screen is doubled
Answer:
Wavelength
Explanation:
Electromagnetic Waves have different wavelengths.
They only differ from each other in wavelength. Wavelength is the distance between one wave crest to the next.
Is there suppose to be an image?
Without a bulb energy cant go through and it would be an open circuit blocking the energy from coming out.
