Answer:
True The grid with more slits gives more angle separation increases
True. The grating with 10 slits produces better-defined (narrower) peaks
Explanation:
Such a system can be seen as a diffraction network in this case with different number of lines per unit length, the expression for the constructive interference of a diffraction network is
d sin θ = m λ
where d is the distance between slits or lines, m the order of diffraction and λ the wavelength.
For network with 5 slits
d = 1/5 = 0.2
For the network with 10 slits
d = 1/10 = 0.1
let's calculate the separation (teat) for each one
θ = sin⁻¹ (m λ / d)
for 5 slits
θ₅ = sin⁻¹ (m λ 5)
for 10 slits
θ₁₀ = sin⁻¹ (m λ 10)
we can appreciate that for more slits the angle increases
the intensity of a series of slits is
I = I₀ sin²2 (N d/2) / sin² d/2)
when there are more slits (N) the peaks have greater intensity and are more acute (half width decreases)
let's analyze the claims
False
True The grid with more slits gives more angle separation increases
False
True The expression for the intensity of the diffraction peaks the intensity of the peaks increases with the number of slits as well as their spectral width decreases
False
Answer:
N = 195 turns
Explanation:
The inductance of the inductor, L = 500 μH = 500 * 10⁻⁶H
The length of the tube, l = 12 cm = 0.12 m
The diameter of the tube, d = 4 cm = 0.04 m
Radius, r = 0.04/2 = 0.02 m
Area of the tube, A = πr² = 0.02²π = 0.0004π m²

The inductance of a solenoid is given by:


Answer:
1.5 m/s.
Explanation:
The Speed of a wave is the product of the wavelength and its frequency or it is the ratio of it wavelength and its Period. It can be expressed mathematically as
V = λf or λ/T .............................. Equation 1
Where V = speed of the wave travelling on the string, λ = wavelength of the wave, T = period of the wave, F = frequency of the wave.
Given: λ = 1.8 m ( distance it takes to repeat itself), T = 1.2 s (Time taken to complete a full cycle)
Substitute into equation 1
V = 1.8/1.2
V = 1.5 m/s.
Hence the wave is 1.5 m/s fast.
