Question
please each questions answer. just summarize and slmplify answer please that is physics.
1. Explain the laws of reflection and refraction.
2. Define the index of refraction.
3. If you want to measure the index of refraction for an unknown optical material,
what is your experimental plan?
4. Discuss the differences between concave and convex mirrors.
Explanation / Answer
1.)The law of reflection states that the incident ray, the reflected ray, and the normal to the surface of the mirror all lie in the same plane. Furthermore, the angle of reflection is equal to the angle of incidence
The law of refraction, which is generally known as Snell's law, governs the behaviour of light-rays as they propagate across a sharp interface between two transparent dielectric media. ... The law of refraction states that the incident ray, the refracted ray, and the normal to the interface, all lie in the same plane.
2.)The index of refraction is defined as the speed of light in vacuum divided by the speed of light in the medium. The indices of refraction of some common substances are given below with a more complete description of the indices for optical glasses given elsewhere.
n = c/v
3.)we pass the light through it and find the angle of incidence and angle of refration
and then use snail law to calculate the refractive index of material
Sin i / Sin r = n2/n1
4.,) reflactng surface of concave in bulged inward but the reflecting surface of the convex mirror is bulged outwards. (2) Concave mirror produces real and iverted images (except when the object is placedbetween pole and focus. When the object is placedbetween F and P, concave mirror produces virtual and erect image)
