Answer:
1.3 x 10⁻⁴ m
Explanation:
= wavelength of the light = 450 nm = 450 x 10⁻⁹ m
n = order of the bright fringe = 1
θ = angle = 0.2°
d = separation between the slits
For bright fringe, Using the equation
d Sinθ = n
Inserting the values
d Sin0.2° = (1) (450 x 10⁻⁹)
d (0.003491) = (450 x 10⁻⁹)
d = 1.3 x 10⁻⁴ m
Answer:
D 9.8 m/s^2
Explanation:
The force of gravitational gravity on earth is 9.8 m/s^2
Answer:
x' =2000201.2 λ
Explanation:
Given that
m = 3
We know that path difference is given as
Δx = m λ
x' - x = m λ
Given that x= 2,000,198.2λ
x'=Distance between far distance slits
x=Distance between near distance slits
Now by putting the values in the above equation e get
x' = 2,000,198.2λ + 3 λ
x' =2000201.2 λ
Therefore the answer will be 2000201.2 λ.
Answer:
(C) apparently written incorrectly - it should be 29.9 +- .3 K
(read 29.9 plus or minus .3 K)
