). According to the , the ratio of the sine of the angle of incidence ( ) to the sine of the angle of refraction ( ) is constant for two given media:
) of a medium shows how many times the speed of light in a vacuum ( ) is greater than its speed in the medium ( 3 in the 11th-grade physics curriculum by S
. Typically, for standard glass, the result should be approximately . 4. Conclusion ). According to the
Connect the entry and exit points to visualize the refracted ray inside the glass. Use a protractor to measure the angle of incidence ( ) and the angle of refraction ( for standard glass
Calculate the refractive index for each trial using the formula
The subject of laboratory work No. 3 in the 11th-grade physics curriculum by S.A. Tikhomirova and B.M. Yavorsky is .
