Filters and the Absorption of Different Wavelengths of Light

The video tutorial explains how objects transmit or absorb different wavelengths of light. It begins by discussing how the sun and artificial sources emit white light, which is a combination of all visible light wavelengths. Filters are introduced as transparent materials that transmit specific wavelengths while absorbing others. The video provides examples of blue and red filters, explaining how each allows only its respective color to pass through while absorbing other wavelengths.
