Answer:
(a) λ = 0.496 um (b) S =2π Δ d sinθ/ λ (c) I =gI₀ (d) For the central diffraction peak, a total of 5 interference maxima are present or available.
Note: find an attached copy of a part of the solution to the given question below.
Explanation:
Solution
Recall that:
d = 6.6 um
λ₀ =d/10
λ₀ = 6.6 um
Now,
(a) We find the wavelength λ of the light in water.
Thus,
λ water = (λ₀ )/n
= 0.66/1.33
So,
λ water = λ = 0.496 um
(b) We find the phase difference between the waves from slit 1 and 2
Now,
if a <<d and a<<λ
Then the path difference between the rays will be
Δ S₂N = Δ d sinθ
Thus, the phase difference becomes,
S = 2π Δ/λ is S= 2π Δ d sinθ/ λ
<u>(</u>c) The next step is to derive an expression for the intensity I as function of O and other relevant parameters.
Now,
Let p be the point where these two rays interfere with each other.
Thus,
The electric field vector coming out from slot and and slot 2 is
E₁= E₀₁ cos (ks₁ p - wt) i
E₂ = E₀₂ cos (ks₂ p - wt) i

Answer:
See the answer below
Explanation:
a. The volume in the first measuring cylinder reads 70
while that of the second reads 95
. Hence;
V1 = 70 
V2 = 95 
b. <u>An object will always displace its own volume in a liquid</u>. Hence:
Volume V of the rock sample = V2 - V1
= 95 - 70 = 25 
c. Mass of A = 102 g
Volume of A = 25 
<em>Density = mass/volume</em>
Hence, density of A = 102/25 = 4.08 g/
Answer:
26.4 m/s
Explanation:
4 g = 0.004 kg
By the law of momentum conservation, the momentum before and after the impact must be the same



So the speed of the block after the impact is 26.4 m/s
