How does a plane mirror work

Physics
1 answer:
Nastasia [14]2 years ago
5 0

Answer:

Plane mirrors work because the light rays create a virtual image behind the mirror. Light rays from the object strike the mirror and reflect according to the law of reflection. ... Therefore, our eye and brain track the light rays backward to a position from which they appear to have come.

Explain how a current is induced in the wire?
Nastasia [14]

Answer:

If a coil of wire is placed in a changing magnetic field, a current will be induced in the wire. This current flows because something is producing an electric field that forces the charges around the wire. (It cannot be the magnetic force since the charges are not initially moving). ... that determines the induced current.

What is the thinnest soap film (excluding the case of zero thickness) that appears black when illuminated with light with a wave
Llana [10]

Explanation:

It is given that,

The thinnest soap film appears black when illuminated with light with a wavelength of 535 nm, \lambda=5.35\times 10^{-7}\ m

Refractive index, \mu=1.33

We need to find the thickness of soap film. The soap film appear black means there is an destructive interference. The condition for destructive interference is given by :

2t=m\dfrac{\lambda}{\mu}

t = thickness of film

m = 0,1,2....

\mu = refractive index

t=m\dfrac{\lambda}{2\mu}

t=\dfrac{\lambda}{2\mu}

For thinnest thickness, m = 1

t=1\times \dfrac{5.35\times 10^{-7}\ m}{2\times 1.33}

t=2.01\times 10^{-7}\ m

Hence, this is the required solution.

A 2 kg picture frame sits on a shelf at a height of 0.5 m. how much gravitational potential energy is added to the picture frame
AysviL [449]

The change in gravitational potential energy is A) 15.68 J

Explanation:

The gravitational potential energy of an object is the energy possessed by the object due to its position in the gravitational field.

The change in gravitational potential energy of an object is given by the equation:

\Delta U = mg\Delta h

where

m is the mass of the object

g=9.8 m/s^2 is the acceleration due to gravity

\Delta h is the change in height of the object

In this problem, we have

m = 2 kg is the mass of the frame

\Delta h = 1.3 - 0.5 = 0.8 m is the change in height

Substituting,  we find:

\Delta U = (2)(9.8)(0.8)=15.68 J
