You send a beam of light from a material with index of refraction 1.17 into an unknown material. In order to help identify this
material, you determine its index of refraction by measuring the angles of incidence and refraction for which you find the values 40.1 ° and 36.3 ° , respectively. What is the index of refraction of the unknown material?
The index refraction of the unknown material is 1.08
Explanation:
Light has characteristics of a wave. When light travels or propagates through two media with different index of refraction, the light will bend or will change its speed.
Using Snells' law which is stated mathematically as:
From Snell's law, the refractive index of the unknown material is the ratio of the sine of the angle of incidence in the unknown material to the sine of the angle of refraction in the unknown material.
Membrane potential is describes the difference in electrical charge across a membrane.
The difference in potential between exterior and interior of the biological cell is known as Membrane potential.Generally it is denoted by millivolts like mV and varies from -80 V to -40 V.
