Wavelength of monochromatic light l 589 nm Speed of light c 3 10 8 m s Refractive index m 1. It travels 30 miles in the first hour 45 miles in the second hour and 75 miles in the third hour. In 3 s sound has to travel twice the distance between the reflecting surface and the source.
Formula for distance related to an echo.
The ray of light hitting the surface is called the incident ray. So we know the refraction index for this questionable material times the sine of 30 degrees is going to be equal to the refraction index for a vacuum. So lets figure out the refraction index first. For example A car travels 3 hours.
