How do u figure out the ratio of the refraction index if you have to unknown materials, that of which, one is 1.25 greater than the speed of sound.
You realize, I hope, that the speeds referred to in that equation for index of refraction are speeds of light, not sound!Spectre32 said:Well to figure out the refraction index the formula is liek n= c/v. Therefore knowing the speed of sound is important.
The formula for calculating the refraction index ratio with 2 unknowns is n1/n2 = sin(i)/sin(r), where n1 is the refraction index of the first medium, n2 is the refraction index of the second medium, i is the angle of incidence, and r is the angle of refraction.
The angle of incidence and refraction can be determined by measuring the angle between the incident ray and the normal line, and the angle between the refracted ray and the normal line, respectively. These angles can be measured using a protractor or by using trigonometric functions.
Yes, the refraction index ratio can be greater than 1. This indicates that the speed of light is slower in the second medium compared to the first medium.
The refraction index ratio can be affected by the type of medium, the wavelength of light, the temperature, and the pressure. Different materials have different refraction indexes, and factors like temperature and pressure can change the density of the medium, thereby affecting the speed of light.
No, the refraction index ratio cannot be negative. This would imply that the speed of light in the second medium is faster than the speed of light in the first medium, which is not possible according to the laws of physics.
