• Reflection Reflection when a wave strikes an object and bounces off.
• Reflection incident ray reflected ray Normal Surface.
• Reflection.
• Reflection incident ray reflected ray Normal Surface.

What are the 5 main properties of light?

There are 7 basic properties of light :

• Reflection of light.
• Refraction of light.
• Diffraction of light.
• Interference of light.
• Polarization of light.
• Dispersion of light.
• Scattering of light.

What are the properties of light?

The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum and polarization.

### What are the nature of light?

Light is a transverse, electromagnetic wave that can be seen by the typical human. The wave nature of light was first illustrated through experiments on diffraction and interference. Like all electromagnetic waves, light can travel through a vacuum.

What is the most important property of light?

Which is the property of light that does not change when it travels from one medium to another? The frequency of light does not change when light travels from one medium to another.

What are the properties of light for class 10?

The Characteristics of light :

• Light is an electromagnetic wave.
• Light travels in a straight line.
• Light is a transverse wave, and does not need any medium to travel.
• The velocity of light changes when it travels from one medium to another.
• The wavelength (λ) of light changes when it goes from one medium to another.

## What are the 2 properties of light?

Properties of Light

• Reflection Of Light and Laws Of Reflection.
• Rectilinear Propogation of Light.

What is the nature of light Class 10?

The nature of light is an electromagnetic wave. Light has wavelength and particles. The term “wavelength” is used to describe a wave or object of light.

How is light produced in nature?

The Sun is the major source of light for the earth. The sun is a massive ball of fire, at the center of which nuclear fusion produces massive energy. This energy comes out as heat and light. The light from the sun is one of the major factors behind the sustainability of life on earth.

### What are the 2 nature of light?

In physics, there are two theories by which light can be defined: the first theory defines light as particles and the second theory as waves. When considering measurement equipment such as spectro[radio]meters, which measure light in wavelengths, the second theory is the most suitable to explain light.

How is light made in nature?

Natural sources of light include the sun, stars, fire, and electricity in storms. There are even some animals and plants that can create their own light, such as fireflies, jellyfish, and mushrooms. This is called bioluminescence. Artificial light is created by humans.

What are the properties of light in physics?

REFLECTION OF LIGHT 2. Light 3. Part 1 – Properties of Light Light travels in straight lines: Laser 4. Light travels VERY FAST – around 300,000 kilometres per second. At this speed it can go around the world 7.5 times in one second. 5. Light travels much faster than sound.

## What is the dual nature of light?

• Light has a dual nature. • Depending on the phenomenon or behavior in question, light can be treated either as a wave or as a particle. • To examine this wave-particle duality, we will examine two experimental proofs.

How does light pass through different materials?

Opaque materials – absorb light; do not let light to pass through 2. Transparent materials – allow light to easily pass through them 3. Translucent materials – allow light to pass through but distorts the light during the passage 4. Reflection Light follows the Law of Reflection: “The angle of incidence is equal to the angle of reflection.”

What is meant by regular reflection of light?

Regular/Specular reflection – reflected rays go in one directions; happens in smooth and shiny surfaces; image can be seen 8. Refraction Light follows the Law of Reflection: “The angle of incidence is equal to the angle of reflection.”
