An experiment wanted to find the speed of light in a substance. When a laser beam entered the substance with an incident angle of 30°, the angle of refraction was found to be 22°. What value for the speed of light would the experimenter obtain with this data? (The speed of light in air is approximately 3x10⁸ m/s.)​

Sagot :

Answer:

2.25 × 10 m/s

Explanation:

Using Snell's Law,

[tex]n1 \sin( \alpha ) = n2 \sin( \beta ) \\ (1) \sin(30) = n \sin(22) \\ n = 1.3347 \\ \\ n = \frac{c}{v} \\ 1.3347 = \frac{3 \times {10}^{8} }{v} \\ v = 2.25 \times {10}^{8} \: m {s}^{ - 1} [/tex]
