## What Light energy?

Light is a type of energy that travels through the air and is used to see things. It is made up of tiny particles called photons. When these particles hit an object, they reflect off the object and enter our eyes. This is how we are able to see things.

Light energy can also travel in waves. Waves are made up of crests and troughs. The distance between two crest is called the wavelength. The wavelength Light waves can be different depending on the type of light. For example, visible light has a shorter wavelength than infrared light.

The amount of time it takes for one wave to pass a given point is called the frequency. The frequency of light waves can also be different depending on the type of light. For example, visible light has a higher frequency than infrared light.

## How light energy travel in waves?

Light energy travels in waves. The waves can be either transverse or longitudinal. The vast majority of light that we experience is transverse light, which means that the oscillations are perpendicular to the direction of travel. Sunlight, for example, is composed of transverse waves. Longitudinal waves, on the other hand, have oscillations that are parallel to the direction of travel. Sound waves are an example of longitudinal waves.

## The properties of light energy

Light energy is a type of electromagnetic radiation. This means that it is made up of electric and magnetic fields that travel through the air (or vacuum) at the speed of light.

Light waves are different from other kinds of waves, such as sound waves, because they do not need a medium to travel through. This means that they can travel through a vacuum, which is why we can see stars that are billions of miles away!

Light waves are also different from other kinds of waves in the way that they interact with matter. When light waves hit an object, they can be reflected, refracted, or absorbed.

## The speed of light energy

They key to understanding how light energy travels is in its waves. Waves are fast and light energy travels at the speed of light, which is 186,000 miles per second! The wave properties of light allow it to bend and reflect off surfaces. When you see a beam of sunlight reflecting off a lake, that’s because the waves hit the water and bent (or refracted) off at an angle.

## The direction of light energy

Light energy travels in waves. The direction of the wave is perpendicular to the direction of the light energy.

## The wavelength of light energy

The wavelength of light energy is the distance between two peaks of the wave. The unit for wavelength is usually given in nanometers (nm), although other units such as micrometers (μm) or Angstroms can be used.

The wavelength of visible light ranges from 400 to 700 nm, red having the longest wavelength and violet the shortest. Near-infrared has even longer wavelengths, while ultraviolet has shorter wavelengths.

X-rays and gamma rays have even shorter wavelengths and are not visible to the human eye. All of these types of light energy travel in waves.

## The frequency of light energy

Most people are familiar with the idea of light energy waves, but many do not know how those waves work. Waves are created when the energy travels from the sun and is reflected off of an object. The frequency of light energy is determined by the speed at which the waves travel.

The higher the frequency, the more energy is in the wave. Visible light waves have frequencies that range from 430 to 750 THz. Infrared waves have frequencies that are lower than visible light, while ultraviolet waves have frequencies that are higher.

The distance between two peaks in a wave is called the wavelength. The shorter the wavelength, the higher the frequency and energy of the wave. Gamma rays have very short wavelengths and high energies, while radio waves have very long wavelengths and low energies.

Waves can be described by their amplitude, which is the height of a wave from peak to trough, and their intensity, which is related to the amount of power in a wave. The more energy a wave has, the brighter it will appear.

## The amplitude of light energy

Light energy is a type of electromagnetic radiation. This means that it travels in waves. The distance between two peaks (or two troughs) is called the wavelength. The number of waves that pass a point in one second is called the frequency.

The amplitude of a light wave is the height of the wave from the baseline to the peak (or from the baseline to the trough). A high amplitude means that the wave has a lot of energy. A low amplitude means that the wave has less energy.

## The polarization of light energy

The polarization of light energy is a physical phenomenon that occurs light waves travel through certain materials. When light waves are polarized, they vibrate in a single plane. This can cause the waves to cancel each other out, making the light appear dimmer.

Polarized light is used in many applications, such as sunglasses and LCD screens. It can also be used to study the properties of atoms and molecules.

Light energy can be polarized by passing it through a polarizing filter. This filter allows only wave vibrations that are aligned with its axis to pass through. The axis is the line perpendicular to the plane of vibration.

Polarized light can also be generated by reflecting light off of a surface, such as a mirror. When light reflects off of a surface, the vibrations of the waves become aligned with the surface. This makes the reflected light more polarized than the incident light.

## The diffraction of light energy

Light energy is a type of electromagnetic radiation. Electromagnetic radiation is a type of energy that travels in waves. These waves are made up of oscillating electric and magnetic fields.

Light waves can be diffracted, or bent. This happens when the waves encounter an obstacle in their path. The amount of diffraction depends on the wavelength of the light and the size of the obstacle.

Shorter wavelength light, such as blue light, is more easily diffracted than longer wavelength light, such as red light. This is why blue light is scattered more in the atmosphere than red light.

The size of the obstacle also affects diffraction. The larger the obstacle, the more the light will be bent. This is why objects appear to be blurry when viewed through a small opening.

Diffraction occurs because light travels as a wave. Wave properties such as diffraction are not exhibited by particles such as electrons or atoms.
