Grade 12 Physics: Waves and Light

A water wave passes under a dock with a period of 4 seconds. Calculate the frequency of the wave. Open question →

A light wave has a wavelength of \( 600 \, \text{nm} \) in air. Calculate its frequency. (Assume the speed of light \( c = 3.0 \times 10^8 \, \text{m/s} \).) Open question →

A beam of light strikes a surface at an angle of incidence of 30°. If the angle of refraction is 20°, calculate the index of refraction of the second medium. Open question →
