What happens if light passes through a filter?
It depends on what kind of filter it is. A blue light filter, will cause the image appear to be bluer, while a red light filter will make the image reddererrr... ^^
Can each type of image be projected on screen explain?
A virtual image cannot be projected onto a screen, because the light rays never actually to through the point where they seem to come from. A real image can be projected onto a screen, because the light rays do actually go through the point where they focus.
What is the source of radiation of a dissecting microscope?
The source of radiation of a dissecting microscope is light. The illuminated light is what will cause the image to appear in three-dimensional format.?æ
Why does an object submerged in water appear closer to the surface than it actually is?
Because - light reflecting back to the observer from the object is bent as it leaves the water. This makes the object appear to be in a different place to where it actually is.
What happens to an image when the focal length of the lens is reduced?
If the Object you are 'focused' on stays in the same relative position to the lens, then the image will appear SMALLER on the Focal Plane. For example, the image using a 50mm lens will be LARGER than using a 28mm lens.
When is the image said to be real or virtual image?
An image is called real if the light rays coming from a point(point on object) meet at a point after reflection or refraction. An image is virtual if the light rays do not actually meet after reflection or refraction. These rays appear to come from a point which is the point where we say virtual image is formed.
How are virtual images and real images different?
A virtual image is a copy of an object formed at the location from which the light rays appear to come. Whereas a real image is a copy of an object formed at the point where the light rays actually meet.
What is the appearance of an image viewed in the light microscope?
they appear back wards
What is bright dancing?
It where you draw something with a light and it comes out as an image.
What can cause an image to appear blurred using a microscope?
The light so bright.
What are the similarities between real and virtual images?
A real image is when the light rays form an image that is on the same side as the object that is being reflected. Meanwhile a virtual image is when the light rays appear to form an image. The real image will appear through the lens and be reflected on the other side while the virtual image will appear in the lens itself and will only reflect a blurry image through the lens. In a diagram, a real image is the solid lines, while the virtual image is represented by dashed lines. Both types are the effect of light being reflected off of or through a mirror or a lens.

In a light microscope the lenses does what to the image?
makes objects look closer than they appear
What is a virtual image?
In optics, a virtual image is an image in which the outgoing rays from a point on the object never actually intersect at a visable point. However, if these rays were stretched out they would intersect at a point behind the mirror/surface.
What are the examples for real and virtual images?
example of Real Images are the images seen on screen on cinema and image form in the human retina. also image produced on the camera. An example of a Virtual image is your image in a flat bathroom mirror. The light rays reflect away from the mirrors and do not actually pass through the image of yourself. The general rule of thumb to follow is: if the light rays ACTUALLY pass through the image, then it is a real image.
Why do things in a pool appear closer than they actually are?
The refractive index of air (n=1.00) is less than the refractive index of water (1.33) so when light rays transmit through the water the rays are refracted and produce a "virtual image" making the object appear closer.
Can each type of image be projected on screen explain?
A virtual image cannot be projected onto a screen, because the light rays never actually to through the point where they seem to come from. A real image can be projected onto a screen, because the light rays do actually go through the point where they focus.
