Answer:
we conclude that visible light is that electromagnetic wave that makes up the colors of a rainbow seen after a storm.
Hence, option A is correct.
Explanation:
Generally, after the storm, we can witness the presence of a rainbow with our naked eyes. Rainbow, visible to our eyes, consists of all the seven constituent colors of white light. Those seven colors range from violet to red, all having different wavelengths. When water particles present in our atmosphere get exposed to light, all the constituent colors of a white light tend to deviate at a variety of angles. It happens due to their refraction through water particles; thus, a spectrum is obtained.
As we cannot see X-rays, UV rays, and infrared waves through our naked eye, visible light is the kind of electromagnetic wave that makes anyone able to see the objects.
Please note that all the constitute colors of a beautiful rainbow associate with the visible region of the electromagnetic spectrum.
Therefore, we conclude that visible light is that electromagnetic wave that makes up the colors of a rainbow seen after a storm.
Hence, option A is correct.
The time it takes for the Moon to rotate once around its axis is equal to the time it takes for the Moon to orbit once around Earth
Answer:
0.203 micro meter
Explanation:
for destructive interference that appearsblack, use the formula
2 t = m λ / u (where m = 0 1 2 3 ... is order of minima)
where t = tickness,
u is the ref index = 1.32
Wavelenth λ = 535×10^-9 meter
for t (minimum) m = 1 (as m=0 is ruled out as t>0)
t = 1× 535×10^-9/2×1.32
t (min) = 202.65×10^-9 meter
OR
t (min) = 0.203×10^-6 meter = 0.203 micro meter

Answer:
3.528×10² V.
Explanation:
potential difference: This is the work done when one coulomb of charge moves from one point to another in an electric field. The S.I unit of potential difference is volt. The formula of potential difference is given as,
V = kq/r..................... Equation 1
And
E = kq/r² .................. Equation 2
Comparing equation 1 and equation 2,
V = E×r............................. Equation 3
Where V = potential difference, E = Electric field between the plate of the capacitor, r = distance between the plate.
Given: E = 6.3×10⁵ V/m, r = 0.56 mm = 0.00056 m.
Substitute into equation 3,
V = 6.3×10⁵×0.00056
V = 3.528×10² V.
Hence the potential difference of the plate = 3.528×10² V.
