WebLight Reflection and Refraction Questions Page: 168 1. Define the principal focus of a concave mirror. Answer-Light rays that are parallel to the principal axis of a concave mirror converge at a specific point on its principal axis ... 1.52 Diamond 2.42 Answer-Light travels faster in water as compared to kerosene & turpentine, as the refractive ... WebThe refractive index is a property of a medium through which light can pass. Its value is calculated from the ratio of the speed of light in vacuum to that in the medium. For example, the refractive index of glass is 1.516 and that of water is 1.333. The amount of bending of light during refraction depends on the difference between the ...

Web72 rows · Many materials have a well-characterized refractive index, but these indexes often depend strongly upon the frequency of light, causing optical dispersion.Standard … WebThe refractive index n of a medium (e.g., water, olive oil, etc.), also called the index of refraction, is defined as the quotient of the speed of light in vacuum c and the speed of light in the medium v.It is a dimensionless number that depends on the temperature of the medium and the wavelength of the light beam. In simple words, the index of refraction … truscott place aspen

WebMar 4, 2024 · Assuming that light travels from air to glass, the angle of incidence is 30°, and the angle of refraction is 20°. To calculate the refractive index, follow these steps: Identify the refractive index of air: n ₁ = 1. Modify Snell's law to find the refractive index of glass: n ₂ = n ₁sin (θ₁)/sin (θ₂). Enter data: n ₂ = 1×sin (30 ... philippine tourism during covid 19
