Answer:
2.2 µm
Explanation:
For constructive interference, the expression is:
Where, m = 1, 2, .....
d is the distance between the slits.
Given wavelength = 597 nm
Angle, = 15.8°
First bright fringe means , m = 1
So,
Also,
1 nm = 10⁻⁹ m
1 µm = 10⁻⁶ m
So,
1 nm = 10⁻³ nm
Thus,
<u>Distance between slits ≅ 2.2 µm</u>
The emissivity of the earth is 0.5
The emissivity of the earth is calculated by the Stefan's law
Answer:
Solar flare
Explanation:
In the Sun when there is an sudden increase in brightness which is generally accompanied by a coronal mass ejection it is known as a solar flare. Solar flares occur close to Sun spot.
Coronal mass ejection is the release of matter (plasma) with a strong magnetic field from the corona of the Sun.
The energy they release ranges between which is comparable to 100-megaton hydrogen bombs exploding simultaneously
