Answer:
The height of mountain in meter will be 106.2732 m
Explanation:
We have given height of mountain = 348 ft,8 in
We know that 1 feet = 0.3048 meter
So 348 feet
And we know that 1 inch = 0.0254 meter
So 8 inch
So the total height of mountain in meter = 106.07+0.2032 = 106.2732 m
The height of mountain in meter will be 106.2732 m

Answer:
λ = a
Explanation:
This is a diffraction exercise that is described by the expression
a sin θ = m λ
sin θ = m λ/ a
the first zero of the diffraction occurs for m = 1
sin θ = λ / a
angles are generally very small and are measured in radians
sin θ = θ = y / x
we substitute
the width of the central maximum is twice the distance to zero
w = 2y
in the exercise indicate that this width is equal to twice the distance to the screen (2x)
W = 2x
2y = 2x
we substitute
1 = λ/ a
λ = a
we see that the width of the slit is equal to the wavelength used.
