Why is a magnifying glass considered an Optical Device?
Because a magnifying glass is made of of convex lens. It converses light rays and magnifies the objects seen through it.
Why diverging lens cannot be used as magnifying glass?
a diverging lens can not be used as a magnifying glass becuase a diverging lens( concave) lens diverges the the rays cousing the image to not be erect, but upside down. While magnifying glass ( convex) is used as it is a converging lens which focuses the rays in one point of an objects making it magnifies and erect.( right way up)
Why do objects burn when light shines through a magnifying glass?
well usually you need something stronger then a magnifying glass, but it increases the heat from the sun and burns something in its radius
Will a magnifying glass light something with a lamp?
If you mean 'set fire to something' then no, there is most unlikely to be enough energy in a normal light beam even when it's focussed with a magnifying glass. It does depend on the power of the light, of course. How many watts do you think it will take
How are magnifying lenses constructed?
Have you ever wondered how a magnifying glass is constructed? A magnifying glass is constructed by using a convex lens to curve and magnify objects. A magnifying glass is also constructed out of glass.
Why is a magnifying glass considered an Optical Device?
Because a magnifying glass is made of of convex lens. It converses light rays and magnifies the objects seen through it.
An instrument that produces images by focusing light rays is called a?
a magnifying glass, a telescope or microscope all do this.
Why does a magnifying glass must be held so that the light from the sun forms a circular dot to burn paper?
A magnifying glass forms a circular dot where it focuses rays of light from the sun. The focus of a magnifying glass is at a distance from the surface of the glass itself. So a magnifying glass must be held [approximately] perpendicular to the line joining the sun and the target, and at a distance from the target which equals the focal length of the lens.
How do lenses of a light microscope make an object look larger?
The lenses of a microscope have shapes that bend light rays, and when we view those bent rays, the object appears larger--a magnifying glass has the same effect.
What is the different between a magnifying glass and a compound light microscope?
A magnifying glass has one lenses and a compound light microscope has 2 lenses
If you use a magnifying glass focus the rays of the sun could it make a fire?
Yes, if you focus the rays of the sun using a magnifying glass on a small and dry surface, such as paper or leaves, it can concentrate the light and heat enough to start a fire. This is due to the magnifying glass converging the sunlight onto a small area, increasing the intensity of the heat.
What are examples of light reflections?
A magnifying glass reflecting light.
If you look through the bottom of a glass beaker everything looks distorted why?
The glass at the bottom is not of uniform thickness and not of optical quality. The rays of light from the objects that you are looking at are, therefore diffracted and absorbed in different ways. This causes the distortions.
What is a magnifying glass made of?
the magnifying glass has a convex lens and it curves to magnify objects.
Why diverging lens cannot be used as magnifying glass?
a diverging lens can not be used as a magnifying glass becuase a diverging lens( concave) lens diverges the the rays cousing the image to not be erect, but upside down. While magnifying glass ( convex) is used as it is a converging lens which focuses the rays in one point of an objects making it magnifies and erect.( right way up)
What principle of light a magnifying glass make use of?
The refraction.
Can you heat water a magnifying glass with an artificial light source instead of the sun?
Sure. But the magnifying glass can't squeeze any more heat out of your light sourcethan what the source has without the magnifying glass.The only thing the magnifying glass does is take all of the light ... and maybe heat ? ...that hits the magnifying glass and focus it down to a very small area. It has no moreheat or light to work with than what enters the glass.The most efficient way to heat water with a light bulb is to shine the bulb straight upand hang the pot over it.
