Answer:
Second order line appears at 43.33° Bragg angle.
Explanation:
When there is a scattering of x- rays from the crystal lattice and interference occurs, this is known as Bragg's law.
The Bragg's diffraction equation is :
.....(1)
Here n is order of constructive interference, λ is wavelength of x-ray beam, d is the inter spacing distance of lattice and θ is the Bragg's angle or scattering angle.
Given :
Wavelength, λ = 1.4 x 10⁻¹⁰ m
Bragg's angle, θ = 20°
Order of constructive interference, n =1
Substitute these value in equation (1).

d = 2.04 x 10⁻¹⁰ m
For second order constructive interference, let the Bragg's angle be θ₁.
Substitute 2 for n, 2.04 x 10⁻¹⁰ m for d and 1.4 x 10⁻¹⁰ m for λ in equation (1).


<em>θ₁ </em>= 43.33°
Answer:
Here the circuit in which a 4Ω resistor resistor is connected in series and two 8Ω resistor resistors are connected in parallel. Also, ammeter and voltmeter connected in series and parallel circuit respectively.
Now,
The maximum power of each resistance is 16 W
The 4Ω resistor is linked in series with the circuit.
so, P o w e r = I
two
R, here i is the current through the resistor resistor R
1 6 = I
two
∗ 4 Ω
i = 2A
Now 2A passes through parallel resistors of 8Ω resistance.
we know that, in parallel, the potential difference must be constant,
the current is divided into two parts, because the same resistance current in each resistance will be half. then the current through each resistor in parallel is
2 A
two
.
= 1 A
So finally the current through the 4Ω resistor = 2 A
current through each 8Ω resistor = 1 A
