When the atoms of an object vibrate at the same frequency as light rays what happens to the rays?
they are asorbed.
How do objects reflect light to show different colors?
In the visible spectrum of light, all colors have difference frequencies of wave lengths. So, an object that is green would absorb all the frequencies of light with in the spectrum except green, the light reflected from the object then hits our retina and then our brain tells us to interpret that object to be green. The frequencies that are absorbed in to the object are then converted into energy. That's why when you wear black cloths, black absorbs all visible light, you feel warmer, because the light it absorbs is converted into heat. And white would the opposite from that. If you are wondering why they would reflect that certain color, it is because all atoms and molecules have electrons. Electrons in atoms have a natural frequency that they vibrate when light hits them. The light with the same frequency as the natural frequency of the electrons in the atoms would be reflected.
When the path of light is blocked by an object what happens?
If the object is opaque to the frequency of light impinging on it, some of the light will be reflected and the rest will be converted to heat in the opaque object.
How does the frequency of re-emitted light in a transparent material compare with the frequency of the light that stimulates its re-emission?
The frequency of emitted light in a transparent object is the same as light that stimulates its re-emission.
What cause an object to resonate?
Applying a force at the same rate as the natural frequency will cause resonance. If both the frequencies coincide with each other, they form a wave of double the amplitude. If the crest of one frequency and the trough of the other meet, they cancel out each other and the displacement is 0.

Some electrons in atoms vibrate at a characteristic frequency that produces white light True Or False?
False.
Why are certain colors absorbed into some objects but not others?
colors are different frequencies of light. atoms in objects vibrate in specific frequencies too. objects with atoms vibrating in the frequency corresponding to the color absorb that color and reflect the other frequencies they can't absorb. the color of an object is basically the frequency of light that it can't absorb.
Can an object vibrate at the wavelength of light?
No object can vibrate at the wavelength of light. wavelength of light depends on the intensity of light and electron movements.

What physical phenomenon is causing each dye to absorb light of one or more colors and transmit light of other colors?
In a spectrometer, each dye will absorb light of certain colors and transmit light of other colors because of the nature of the atoms of the object and the frequency of the light. If the frequency of the light is the same as the frequency that the electrons in the atoms are vibrating, then the light will be absorbed and transferred into vibrational motion.
When you add energy to matter the particles move faster?
Thermal energy is heat. When something gets hotter the atoms that compose that object vibrate or "wave" at a higher frequency. However, if you shoot a particle through a particle accelorator, the thermal energy of that object is not relevant to the kinetic energy (or speed/momentum) of that object. As an example, if one had the ability to heat up a light particle, it would have higher thermal energy and would therefore "wave" at a higher frequency. But the speed of light would remain constant as it always does.
What happen to light of certain frequency that encounters atoms of the same resonant frequency?
The light is absorbed by the atom and excites the atom.
When the path of light is blocked by an object what happens?
If the object is opaque to the frequency of light impinging on it, some of the light will be reflected and the rest will be converted to heat in the opaque object.
How a does a light bulb make light and thermal energy?
When the lightbulb is placed in a bulb holder, a voltage is applied across the metallic filament. As a result, a current of electrons now flows from through the filament. As the electrons flow through the metallic filament, they collide with the atoms in the filament, causing the atoms to vibrate. This vibration is what causes the temperature of the filament to rise. When the temperature of an object increases, it will always radiate thermal energy via black body radiation. A more intuitive explanation, is that the atoms in the object vibrate faster and faster as a function of temperature. As a result, the charges around the atoms will vibrate. When charges accelerate and decelerate, they induce an electromagnetic wave, or what is commonly known as light, which radiates away from the atoms. The wavelength of the light that is emitted from the atoms depends on the vibration of the atoms, or equivalently the temperature of the material. So the faster the vibrations, the higher the frequencies and amplitudes (intensity) of the light. The question is misleading in that it implies that light and thermal energy are two different forms of energy. In fact, light and thermal energy are the exact same thing, but just at different wavelengths. The light that we see in our eyes corresponds to wavelengths in the visible spectrum (450nm - 650nm), whereas thermal radiated energy is at longer wavelengths (infrared). Therefore, when the filament is heated up, the atoms vibrate, which causes light to be emitted over a large spectrum of wavelengths, some of that is visible light and some of that is infrared light (heat). This is how a lightbulb can generate both "light" and "thermal energy."
