What happens to the intensity of light after reflection?

Intensity of reflected light increases with the angle.

Why does the intensity of light decrease?

There is an inverse relationship between distance and light intensity – as the distance increases, light intensity decreases. This is because as the distance away from a light source increases, photons of light become spread over a wider area.

Why does light intensity decrease after reflection?

1) When light is incident on a mirror, part of it gets refracted and the majority of it gets reflected. So, after first reflection the intensity of light is slightly less than that of the original light source.

Does the intensity of the light reflected and refracted depend on the angle of incidence?

The intensity of the reflected light depends on the angle of incidence and also on the direction of polarization.

What changes the intensity of light?

The factors affecting the intensity of light are diffraction. Some of the factors affecting intensity are: The energetic intensity of the source (the initial volume). The distance from the source (the volume at any point along the path). Any modifying elements in the light path (air, clouds, filters, reflectors, etc.)

Why does intensity of light decrease in water?

The amount of refraction, referred to as the refractive index, is affected by both the salinity and temperature of the water. Water molecules, dissolved salts, organic substances, and suspended particulates combine to cause the intensity of available solar radiation to decrease with depth.

Does light intensity increase or decrease with distance?

The intensity or brightness of light as a function of the distance from the light source follows an inverse square relationship. Notice that as the distance increases, the light must spread out over a larger surface and the surface brightness decreases in accordance with a “one over r squared” relationship.

What happens to the intensity of the reflected ray and refracted ray when the angle of incidence increases in the air?

As the angle is increased to greater and greater angles, we would begin to observe less refraction and more reflection. That is, as the angle of incidence is increased, the brightness of the refracted ray decreases and the brightness of the reflected ray increases.

What happened to the intensity of the reflected ray when the angle of incidence was larger than the critical angle?

If the angle of incidence is bigger than the critical angle, the refracted ray will not emerge from the medium, but will be reflected back into the medium. This is called total internal reflection.

What happens when you increase the intensity of light?

Increasing the light intensity (photon energy per second per unit area) increases the rate at which electrons leave the metal, and the electrons have more kinetic energy. Changing the frequency of the light while keeping the intensity constant should not change the rate of electron emission.

What factors affect intensity?

In turn, the main factors affecting earthquake shaking intensity are earthquake depth, proximity to the fault, the underlying soil, and building characteristics—particularly height. Let’s take a look at the latter two (soil and buildings) and how they interact.

Does refraction change the intensity of matter as it absorbs it?

Yes, because intensity decreases as it is absorbed my matter, and because the act of refraction and reflect results in divergence – where you measure refraction you cease to measure reflection and where you measure reflection you cease to measure refeaction.

What is the relationship between reflection and refraction of light?

Reflection and refraction. Light rays change direction when they reflect off a surface, move from one transparent medium into another, or travel through a medium whose composition is continuously changing.

Does the intensity of light depend on distance?

Yes, it does. The intensity or brightness of light as a function of the distance from the light source follows an inverse square relationship. Also, in daily life,we can observe that the intensity decreases with increase in distance.

What is the relationship between refractive index and light intensity?

As mentioned in the other answers, if the medium is linearthen the refractive index is independent of the intensity of light, and the intensity can be related to the electric field amplitude through $I = \\frac{nc\\varepsilon_0}{2} E_0^2$.
