Alright buddy, this time we will discuss about Properties of Light, let’s just gouk into the discussion mate.
As an electromagnetic wave, light has certain properties that provide many benefits to living things on earth. The following are some of the properties of light, in Amongnyes that is:
The nature of light that propagates in a straight line can be proven by observing whether or not an object can transmit light. Objects that are opaque cannot pass the light that hits them. When exposed to light, this object will form a shadow. These objects are classified as dark objects, which means they cannot produce their own light. Examples such as cardboard, plywood, wood, walls, and others.
Meanwhile, translucent objects can transmit light that is about it. These objects are known as light source objects. An example is glass.
2. CReflectable light
Another property of light is that light can also be reflected. Reflection of light consists of diffuse reflection (diffuse reflection) and regular reflection. Diffuse reflection occurs when light strikes an uneven surface and the direction of the reflected light is irregular. While regular reflection occurs when light hits a flat, shiny or slippery surface such as light reflected by a flat mirror and the reflected light has a regular direction. The object that has this characteristic of light is a mirror. Based on the shape of the surface, mirrors are divided into plane mirrors and curved mirrors. There are two types of curved mirrors, namely convex mirrors and concave mirrors. The following is a more detailed description of the mirror.
A plane mirror is a mirror whose surface is not curved. A flat mirror is a mirror that we use every day to make up. The properties of a plane mirror include, (1) the size of the image is the same as the size of the object, (2) the distance between the image is the same as the distance of the object to the mirror, (3) the image on a flat mirror is pseudo or virtual, meaning that the image is seen but cannot be captured by the screen. , (4) the image on an upright plane mirror.
A convex mirror is a mirror whose surface is curved outwards. The image is pseudo or virtual (meaning that the image can be seen but cannot be captured on the screen).
Unlike the case with a convex mirror, a concave mirror has a surface that curves inward. The image of an object in a mirror is erect, enlarged and virtual. If the object is far from the concave mirror, the image is real and inverted.
In everyday life, concave mirrors are usually used as reflectors in lights such as cars, flashlights, spoons, and so on.
3. Light can be refracted
Refraction is a bending event in the direction of light propagation, where light propagates through two substances with different densities. If the incident light comes from a less dense substance to a denser substance, the light will be refracted closer to the normal line.
The following is an example of the refraction of light.
- If you put a pencil in water in a glass, it will look bent.
- Pool the clear water will seem shallow
- Looking at the stars with a telescope
4. Decomposable Light
Another term for the decomposition of light is dispersion. The principle of light decomposition is the decomposition of white light into light of various colors. Here are some examples that illustrate how light can be decomposed.
- Rainbow happens, peagles occur due to the presence of sunlight that seems to be coloredrna is white and is actually composed of color variations described by
- water droplets in the clouds/rain water.
- The color disc that is rotated will give an image of white.
- Happening a halo that seems to revolve around the moon or the sun.
5. Light Can Pass Through Clear Objects
This property of light can be proven by the following examples.
- Sunlight can enter to in a house through windows that have clear glass. If the window glass is covered with a black cloth then light cannot penetrate the window glass.
- When a person walks in the daytime one can see the shadow of his own body, this is explained that light cannot penetrate a person’s body because it is not a clear object, so that only shadows are formed.
This is the end of our discussion about Traits Light, hopefully useful for all of you and don’t forget to leave a comment, okay? J
