Light travel in a straight line of diffraction of its particles called photons.

Answer

B

Answer

Light always travels along a straight line path.

Light is an electromagnetic wave that travels in a straight line from its source. This phenomenon is known as rectilinear propagation of light. Here's why light always travels along a straight line path:

1. Wave nature of light:
Light is composed of electromagnetic waves, which propagate as transverse waves. These waves consist of oscillating electric and magnetic fields perpendicular to each other and perpendicular to the direction of wave propagation. The nature of transverse waves ensures that light travels in a straight line.

2. Law of Reflection:
When light encounters a reflecting surface, it follows the law of reflection. According to this law, the incident ray, reflected ray, and the normal to the surface at the point of incidence all lie in the same plane. The angle of incidence is equal to the angle of reflection. This behavior is possible only if light travels in a straight line.

3. Law of Refraction:
When light passes from one medium to another, it undergoes refraction. The law of refraction states that the incident ray, refracted ray, and the normal to the interface between the two media at the point of incidence all lie in the same plane. The angle of incidence and the angle of refraction are related by Snell's law. Again, this behavior can only occur if light travels in a straight line.

4. Shadows:
When an opaque object obstructs the path of light, a shadow is formed behind it. The shadow has a well-defined edge, indicating that light travels in a straight line. If light followed a zigzag, curved, or circular path, the shadow would not have such a distinct boundary.

5. Light travels at immense speeds:
Light travels at a speed of approximately 3 × 10^8 meters per second in a vacuum. This high speed allows light to cover vast distances in a short period. If light followed a zigzag or curved path, it would take longer to reach its destination, contradicting our observations.

In conclusion, due to the wave nature of light, the laws of reflection and refraction, the formation of shadows, and the immense speed at which light travels, we can confidently say that light always travels along a straight line path.
