What is the relation between refractive index and intensity?

What is the relation between refractive index and intensity?

The intensity of light (as calculated from time average of the poynting vector) is given by I=(1/2)ϵvE20. Here the intensity is dependent on the velocity of light in the medium. The refractive index also depends on the velocity of light.

What is the speed and intensity of light in glass?

Light travels at approximately 300,000 kilometers per second in a vacuum, which has a refractive index of 1.0, but it slows down to 225,000 kilometers per second in water (refractive index of 1.3; see Figure 2) and 200,000 kilometers per second in glass (refractive index of 1.5).

Does voltage change with light intensity?

when the light intensity is greater than 200 W/m2, with the increase of the light intensity, the voltage is approximately the same, and it fluctuates at about 340 V.

Does intensity affect voltage?

The voltage output rises sharply with increasing illuminance (or intensity), but at a certain point attains the maximum level. Afterwards, the rate of change of the voltage with increasing illuminance (or intensity) becomes insignificant.

What happens to current when light intensity increases?

Their resistance decreases as the light intensity increases: in bright light, the resistance of an LDR is low and more current can flow through it.

Is voltage an intensity?

The intensity of current in an electrical circuit is equal to the voltage supplied by the battery divided by the resistance within the circuit. The intensity of the current is directly proportional to the voltage, that is, if a battery provides a higher voltage, the current intensity increases.

What actually is a Volt?

Voltage is an electrical potential difference, the difference in electric potential between two places. The unit for electrical potential difference, or voltage, is the volt. The volt is named in memory of Alessandro Volta. One volt equals one joule per coulomb.
