Solving for Angle of Incidence and Speed of Light in Rock Salt - советы от нейросети

Опрелелите угол падения света на каменную соль, если угол преломления 20°. Показатель преломления каменной соли равен 1,54. Какова скорость света в каменной соли?

To find the angle of incidence of light on rock salt, we can use the Snell's law equation $sin heta_i = n_i sin heta_t$, where $n_i$ is the refractive index of the incident medium and $sin heta_t$ is the refractive index of the transmitted medium. For rock salt, the refractive index ($n_i$) is given to be 1.54 and the angle of refraction ($ heta_t$) is 20°. Plugging these values into the equation, we get the angle of incidence ($ heta_i$) to be approximately 12.93°.

Now, to find the speed of light in rock salt, we can use the equation $v = rac{c}{n}$, where $v$ is the speed of light in the medium, $c$ is the speed of light in vacuum (approximately 3x10⁸ m/s), and $n$ is the refractive index of the medium. For rock salt, the refractive index is again 1.54. Plugging in these values, we get the speed of light in rock salt to be approximately 1.95x10⁸ m/s.

Therefore, to summarize, the angle of incidence of light on rock salt is about 12.93° and the speed of light in rock salt is approximately 1.95x10⁸ m/s.
