In the two-slit experiment, for the condition of bright fringes, the value of m = +2 corresponds to a path difference of λ.
melisa1 [442]

Answer:

False

Explanation:

We know that if path difference is even multiple of wavelength then bright fringes are formed and if path difference is odd multiple of wavelength then dark fringes are formed .

For bright fringes

Path difference Δx = m λ

m = 0 , 2 , 4 , 6.......

If m = 2 then the path difference will be

Δx = 2 λ

therefore the above statement if false.

False

The equation for the speed of an electromagnetic wave is
igomit [66]

Answer:

c = 1 / √(ε₀*μ₀)

Explanation:

The speed of the electromagnetic wave in free space is given in terms of the permeability and the permittivity of free space by

c = 1 / √(ε₀*μ₀)

where the permeability of free space (μ₀) is a physical constant used often in electromagnetism and ε₀ is the permittivity of free space (a physical constant).

oee [108]

The kinetic molecular theory explains that all matter is composed of particles constantly moving in random directions. These particles are gaseous particles. When a particle has the freedom to move freely in its surrounding without care of the bonding between them, they are gaseous particles.

A ray diagram shows that an object is placed between the focal point and the vertex of a convex mirror. What are the characteris
Aleonysh [2.5K]
The correct answer is: <span>smaller than object, virtual and upright.
</span>
When the object is placed between the focal point and the vertex of a convex mirror, then the image formed will be <span>located behind the convex mirror. It will be virtual image and an upright image but reduced in size (i.e., smaller than the object)</span>

Light travels through a liquid at 2.25e8 m/s. What is the index of refraction of the liquid?
Pavlova-9 [17]

Answer:

The index of refraction of the liquid is n = 1.33 equivalent to that of water

Explanation:

Solution:-

- The index of refraction of light in a medium ( n ) determines the degree of "bending" of light in that medium.

- The index of refraction is material property and proportional to density of the material.

- The denser the material the slower the light will move through associated with considerable diffraction angles.

- The lighter the material the faster the light pass through the material without being diffracted as much.

- So, in the other words index of refraction can be expressed as how fast or slow light passes through a medium.

- The reference of comparison of how fast or slow the light is the value of c = 3.0*10^8 m/s i.e speed of light in vacuum or also assumed to be the case for air.

- so we can mathematically express the index of refraction as a ratio of light speed in the material specified and speed of light.

- The light passes through a liquid with speed v = 2.25*10^8 m/s :

                         n = c / v\\\\n = \frac{ 3*10^8 }{2.25*10^8} \\\\n = 1.33

- The index of refraction of the liquid is n = 1.33 equivalent to that of water.
