What is the difference between giving off light and reflecting light?
Giving off is emitting it and reflecting light is reflecting it
When light bounces off the surface of an object the light is in a different direction?
Yes, when light bounces off the surface of an object, it undergoes reflection which results in a change in the direction of the light. This change in direction is determined by the angle of incidence and the angle of reflection, according to the law of reflection.
Is temperature change a physical or chemical change?
Temperature is the perception we have of the vibrational energy of the molecules in any substance. The faster they vibrate, the hotter the object. So the answer is physical.
When energy is given off as heat the physical change is said to be?
Exothermic
How do i change a direction of a light beam?
To change the direction of a light beam, you can use mirrors or lenses to reflect or refract the light in the desired direction. Adjusting the angle of the mirror or lens will change the direction of the light beam. Alternatively, you can physically move the light source or the object the light is reflecting off of to change the direction of the beam.
Is giving off light a physical or chemical change?
I would think it to be a Physical Change. Not chemical.
When a firecracker explodes giving off light and heat and breaking the wrapper into many pieces is that a physical change chemical change or both?
This is both a physical and chemical change. The explosion involves the release of energy (heat and light), which is a chemical change due to the breaking of chemical bonds. The breaking of the wrapper into many pieces is a physical change as it does not involve any change in the chemical composition of the materials.
Pouring milk in you r oatmeal - Physical or chemical?
It would be physical change because the substance doesn't change. Signs of chemical changes would be absorbing, liberating (releasing) heat, fizzing, changes of color,or giving off light.
What are Fireworks exploding in the sky and giving off light are an example of?
Exothermic Change
Fireworks exploding in the sky and giving off light are an example of a(n)?
chemical change
What is the difference between giving off light and reflecting light?
Giving off is emitting it and reflecting light is reflecting it
In a firework show the fireworks explode giving off heat and light is this a chemical change why?
It is a chemical change because the chemical composition is changed during this reaction.
Is a firefly giving off light a chemical or physical change?
It's not a change at all. It is simply what the firefly does. But it is a result of a chemical change within the firefly. A chemical reaction involves a transfer of energy. In this case, the energy would go into creating light waves from the molecules in the firefly, causing it to glow.
5 examples of science?
Change in temperature, gaseous bubbles, giving off light, change in color, change in properties. These are chemical changes, but it is still five examples of science.
Is breaking off a branch of a tree a physical change?
Breaking off a branch of a tree is a physical change.
Is a light bulb a chemical or physical change?
A light bulb is not a change in and of itself but the process by which it gives off light is physical. While an electric current causes a given component of the bulb to glow (it may be the filament of an incandescent bulb or the vapor in a fluorescent one), but that substance does not change its chemical identity.
When change oil light come on and off on and off?
Change your oil/filter and reset the light.
