The Magic of Light

Exploring the enchanting properties and phenomena of light that captivate our senses and shape our world.

The Magic of Light

• Reflection of Light: The phenomenon of light bouncing off a surface and changing direction.
• Law of Reflection: Angle of incidence is equal to the angle of reflection.
• Types of Reflection: Regular reflection (mirror-like) and diffuse reflection (scattered).
• Applications: Mirrors, shiny surfaces, photography, and more.

Multiple Choice

What is the phenomenon of light bouncing off a surface and changing direction called?

• Reflection of Light

• Refraction of Light

• Diffraction of Light

• Scattering of Light

Reflection of Light

Trivia: When light reflects off a surface, it follows the law of reflection, which states that the angle of incidence is equal to the angle of reflection. This phenomenon allows us to see ourselves in mirrors and objects around us. Reflection is also used in various optical devices, such as telescopes and cameras, to capture and redirect light.

The Magic of Light

• Refraction of Light: The bending of light as it passes from one medium to another.
• Causes: Change in speed and direction due to change in medium.
• Principle: Light bends towards the normal when entering a denser medium and away from the normal when entering a less dense medium.
• Applications: Lenses, prisms, optical fibers, mirages, rainbows, etc.

Multiple Choice

What is the principle of refraction of light?

• Light bends towards the normal when entering a denser medium and away from the normal when entering a less dense medium.

• Light changes speed and direction due to change in medium.

• Refraction of light causes the bending of light as it passes from one medium to another.

• Refraction of light is used in lenses, prisms, optical fibers, mirages, rainbows, etc.

Principle of Refraction

Trivia: Light bends towards the normal when entering a denser medium and away from the normal when entering a less dense medium. This phenomenon is used in various applications such as lenses, prisms, optical fibers, mirages, and rainbows. Refraction of light occurs due to the change in speed and direction as it passes from one medium to another.
