Because usually the sun's light will focus on the glass and will cause a fire. Not a good thing. Definitely not a good thing.
Black cat, Frosted glass and cloth.
The is usually a glass mirror at the bottom of the microscope to project light up into the thing where you put the object. Do not cover the glass, or you wont be able to see the material you are studying. Also if the is no sunlight, use a light bulb or something...
No the worse thing that would happen is that you shine the light into your eye if you point it at your eye. Just change them when all the lights are off and dont touch the glass part of the new bulb or if will shorten its life span.
yes it is a chemical change because it turned into something new a scultureWRITTEN BY ISABELLA GARCIAIN ROGERS MIDDLE SCHOOL6TH GRADE
On the molecular level, the molecules of glass are unchanged by the physical stress that caused breaking. when glass breaks, the only thing that is affected is the intermolecular bonding, not the intramolecular bonding. In addition, it is observable that although there is somewhat of a shape change, there is no color, heat change or gaseous creation that would imply that a chemical change has taken place.
There is no such thing.
Usually when light hits a piece of glass or plastic the light 'bends' towards something called its 'normal' which is basically just a straight line through any object (must be at a right angle).
Whenever electromagnetic radiation of any kind (light, heat, radio, gamma rays and microwaves are all examples of electromagnetic radiation) travels from one medium to another, the radiation will be refracted because the speed of light in each medium is different. When light travels from air into glass, the glass slows the light down, and the light refracts or "bends" toward the glass, depending on the angle of incidence. (The Angle of Incidence is the angle at which the light hits the glass. ) The amount of refraction (bending) also depends on the wavelength of the radiation, so when sunlight hits the glass at an angle, the glass breaks the "white" light into a rainbow of colors. This is the same thing that happens with a real rainbow, when light hits water droplets and is refracted and broken into different colors.
This is easy to do with a Prism, preferably a long triangular piece of glass. A glass of water can do the same thing, although not as accurate as a triangular shaped prism would.
no such thing as a whatch glass
