As a result, different models describe different aspects of light’s behavior. The electromagnetic wave theory explains light’s ability to travel through a vacuum. The light ray model, on the other hand, can describe interactions between light and matter.

May 24, 2024 · We know that light is a wave based on how it behaves – it exhibits the same properties of other waves we have examined – it interferes with itself, it follows an inverse-square law for intensity (brightness), and so on.

Look in a mirror and you’ll see your reflection. The law of reflection is simple: Whatever angle a beam of light makes as it collides with a mirror is the same angle it will have as it bounces off the mirror’s surface. If you shine a flashlight at a 45-degree angle onto your bathroom mirror, it will bounce off at a 45-degree angle. When you see you...
You know how a straw appears to bend as it sits in a glass of water? That’s due to refraction. The law of refraction states that light waves will bend when they move from one medium (such as air) to another (such as water or glass). This is because each medium has a different density, also known as its “optical thickness.” Imagine running along a b...
Reflection and refraction can work together — often with awesome results. Consider the bending of the sun’s light as it passes through Earth’s atmosphere at a low angle. This tends to happen at sunrise or sunset. Sunlight’s bending, or refracting, paints clouds near the horizon in an array of red and orange hues. You may have also noticed that the ...
Lenses are tools that take advantage of light’s ability to bend. By carefully shaping a piece of glass, optical scientists can design lenses that focus light to make clear images. To magnify the appearance of an object, designers often combine a series of lenses. Most lenses are made from glass that has been ground into a very precise shape with a ...
In one of the universe’s most magnificent tricks, intense gravity can act like a lens. If an extremely massive object — such as a galaxy or a black hole — lies between an astronomer and the distant star they are looking at, that star can appear to be in a false spot (much like the ring at the bottom of a pool). The mass of the galaxy actually warps...
This happens because light reflects off of you, hits the mirror, and then reflects off the mirror to your eye. Reflection occurs when a light wave strikes an object and bounces off it. When light is reflected from a flat mirror, the incoming ray of light is called the incidence ray.
If light is a particle, then why does it refract when travelling from one medium to another? And if light is a wave, then why does it dislodge electrons ? But all behavior of light can be explained by combining the two models: light behaves like particles and light behaves like waves.
May 24, 2024 · When we do that, we narrow down all the possible directions of the light wave motion to a single line, which we call a light ray. This is a directed line that originates at the source of light, and ends at the observer of the light:

Dec 28, 2020 · In plain terms, electromagnetic waves are simply known as light, though the term light is sometimes used to specify visible light (that which can be detected by the eye), and other times is used more generally to refer to all forms of electromagnetic radiation.
