What happens when light energy passes straight through an object? When a light wave hits an object it will either bounce off (reflection), bend (refraction), pass through (transmitted), or be absorbed as heat. Some objects transmit light waves better than others.
What happens when light travels in a straight line?
light travels in straight lines What happens when light strikes an object? it is reflected, absorbed, or transmitted What happens when light strikes a highly reflective surface? bounces of the surface in a straight line at the same angle that it hit the surface What happens when light strikes an opaque object?
What happens when a light wave hits an object?
When a light wave hits an object it will either bounce off (reflection), bend (refraction), pass through (transmitted), or be absorbed as heat. Some objects transmit light waves better than others.
How does light travel through a transparent object?
Transparent objects transmit a lot of light. When light bounces off objects we say it is reflected. Darker objects absorb light more than pale ones do. When an object absorbs light, it warms up. This is because light energy changes into heat energy. We're here to help your child succeed.
What happens to light energy as it travels through a material?
Yes, the light energy usually initially goes into raising some electrons from low-energy states to high-energy states. What happens next depends on the material. Often the electrons settle down, dumping their energy as heat, just thermal shaking of the atoms in the material. It gets warmer.
What happens when light passes through an object?
The phenomena when light passes through the object (a medium) is known as refraction. Refraction is defined as the bending of light ray when it passes from one medium to another.
What is it called when light passes straight through an object?
Materials like air, water, and clear glass are called transparent. When light encounters transparent materials, almost all of it passes directly through them. Glass, for example, is transparent to all visible light. Translucent objects allow some light to travel through them.
How does light travel in a straight line?
Light travels in straight lines Shadows are evidence of light travelling in straight lines. An object blocks light so that it can't reach the surface where we see the shadow. Light fills up all of the space before it hits the object, but the whole region between the object and the surface is in shadow.
When can we say that light travels in a straight line?
Light travels in a straight line can be observed by keeping an object in the path of light. In an atmosphere which is bit dusty, we can see light traveling in a straight line. Light emerging from the torch, train and lamps always travel in a straight line.
Answer
When light waves passes straight through an object, it is called transmission.

What happens when visible light strikes an object?
Any visible light that strikes the object and becomes reflected or transmitted to our eyes will contribute to the color appearance of that object. So the color is not in the object itself, ...
How does visible light interact with objects?
The manner in which visible light interacts with an object is dependent upon the frequency of the light and the nature of the atoms of the object. In this section of Lesson 2 we will discuss how and why light of certain frequencies can be selectively absorbed, reflected or transmitted.
What happens to the vibrations of an object when it is transparent?
If the object is transparent, then the vibrations of the electrons are passed on to neighboring atoms through the bulk of the material and reemitted on the opposite side of the object. Such frequencies of light waves are said to be transmitted.
What does it mean when an object is selectively absorbing light?
When this occurs, objects have a tendency to selectively absorb, reflect or transmit light certain frequencies. That is, one object might reflect green light while absorbing all other frequencies of visible light. Another object might selectively transmit blue light while absorbing all other frequencies of visible light.
What happens when an object is opaque?
If the object is opaque, then the vibrations of the electrons are not passed from atom to atom through the bulk of the material. Rather the electrons of atoms on the material's surface vibrate for short periods of time and then reemit the energy as a reflected light wave.
What happens when a light wave strikes a material with the same vibrational frequency?
If a light wave of a given frequency strikes a material with electrons having the same vibrational frequencies, then those electrons will absorb the energy of the light wave and transform it into vibrational motion.
Why do visible light waves reflect?
Reflection and transmission of light waves occur because the frequencies of the light waves do not match the natural frequencies of vibration of the objects. When light waves of these frequencies strike an object, the electrons in the atoms of the object begin vibrating.
