Understanding Light Waves

The video tutorial demonstrates a machine that models light waves, explaining how wavelength, frequency, and amplitude affect light perception. Initially, the wavelength is set to 670 nanometers with the highest amplitude. The tutorial then shows changes in wavelength to 440 nanometers and adjustments in amplitude, illustrating the impact of these changes on light waves.
