Understanding Light Waves:
* Electromagnetic Waves: Light is an electromagnetic wave, which means it consists of oscillating electric and magnetic fields. These fields are perpendicular to each other and also perpendicular to the direction the wave travels.
* Transverse Waves: Light waves are *transverse* waves. This means the oscillations of the electric and magnetic fields occur perpendicular to the direction the wave is moving. Imagine a rope tied to a pole; if you shake the rope up and down, the wave travels horizontally, but the rope oscillates vertically.
Why We See Light at Right Angles:
* Scattering: When light hits an object, it can be scattered in various directions. Even if the light wave is traveling horizontally, some of it will scatter upwards, downwards, and sideways. This scattered light enters our eyes, regardless of the initial direction of the light wave.
* Diffraction: Another phenomenon called diffraction helps us see light from different angles. Light waves can bend around corners or obstacles. So, even if the light is traveling directly towards you, some of it can diffract around your body and enter your eyes from the sides.
In Summary:
* Light waves oscillate perpendicular to their direction of travel.
* Scattering and diffraction allow light to reach our eyes from various angles, even if we're at right angles to the initial direction of the light wave.
