Answer:
2.4599×10⁻³ m
Explanation:
The relation between the distance of the slits and the angle through which it is passed is:
dsinθ=nλ
where,
n can be any integer
d is the distance between the two slits
λ is the wavelength of light.
Since for the first bright fringe, n=1
The experiment scenario can be drawn with the help of an image shown below.
Given:
d = 6×10⁻⁴ m
λ = 4.1×10⁻⁷ m
6×10⁻⁴×sinθ=(1)
4.1×10⁻⁷
sinθ = 6.8333×10⁻⁴
Since sinθ is very small, so, sinθ = tanθ
tanθ = 6.8333×10⁻⁴
Distance between slit and screen = 3.6 m
So,
tanθ = (The distance if the first bright fringe)/(Distance between slit and screen)
<u>The distance if the first bright fringe = 6.8333×10⁻⁴×3.6 m = 2.4599×10⁻³ m</u>
The answer would be Ultra Violet Radiation.
Explanation would be because, this type of light can cause severe damage to a humans skin.
True because when the independent answer changes, then the dependent variable, which relies on the independent variable, changes.
Answer:
B. Law of Conservation of Mass
Explanation:
In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.
