White light containing the wavelengths between 420 and 720 nm traveling in the air falls on a thin layer n1 = 1.5 and a thicknes

s of 0.000001 m. If this layer is placed on another thin film n2 = 1.4, determine the wavelengths of the light that is not reflected in the air.

The wavelength of the light that are not reflected in the air is,

 λ5= 600 nm, λ6= 500 nm, λ7=428 nm.

<u>Explanation:</u>

  • For the above problem, we have the case as no<n1 and n2 < n1 .
  • so we have(1<1.5;1.4<1.5)To find the wavelengths of the light that is not reflected in the air.
  • Since the phase changes are not common on both the surfaces/
  • we have the formula,   λ=2d n²/m          ( where m=1,2,3,4,5...)
  • solving the problem we get,
  • λ5= 600 nm, λ6= 500 nm, λ7=428 nm
  • The wavelength of the light that are not reflected in the air is,

         λ5= 600 nm, λ6= 500 nm, λ7=428 nm.

1. The statement about Newton's reflecting telescope contains 1 error. Find the error, write it, and
Jlenok [28]

Answer:

i. The error is the rough convex mirror.

ii. This should be replaced with a smooth convex morror.

Explanation:

Reflection is dependent on the surface involved and has two types; diffuse and specular. When the surface is rough, diffused reflection is observed. The surface causes a distortion of the incident light (the rays would be reflected at different angles to one another) after reflection. This makes some rays to interfere with one another. While specular reflection is observed with a smooth surface.

In the statement, the rough convex mirror would produce a distorted reflection which would produce diffused reflection. The effect is that few or no rays (depending on the degree of how rough the surfce is) would be reflected to the other smooth, flat diagonal mirror.

A man pushes an 250-N crate at constant speed a distance of 30.0 m upward along a rough slope that makes an angle of 60° with th
mel-nik [20]

Answer:

6495.19 Joule

Explanation:

F = Weight of the crate = 250 N

d = Distance the cart is pushed = 30 m

θ = Angle of inclination = 60°

The weight of the crate will be resloved into two components

Fdsinθ and Fdcosθ

Work done by the force of gravity is

W = Fdsinθ

⇒W = 250×30×sin60

⇒W = 6495.19 Joule

∴ The work done by the force of gravity is 6495.19 Joule

What does the diameter in meters need to be of a round parachute that the designer has determined needs to have an area of 500 s
Marrrta [24]
Area of a circle is
A= pi r^2
so
500m^2 = 3.14 r2
500/pi = r ^2
152.1549...=r^2
square root both sides
r=12.61566...
d=2r
d=25.2
