It would be Constructive interference. It occurs when two waves collide and make a taller wave.
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>
Answer:
Explained
Explanation:
A student who runs every day is becoming bored with her physical fitness routine and considers quitting. Now in order maintain her fitness routine she needs to break the monotony by changing her exercise regime. She do other activities like play sports two days a week, she do aerobics, she even try some cardio vascular exercises which as good as running. She also try changing her route of running as the new view might inspire her.
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
