1) The invisible energy that causes in use of sensation of vision?
2) The ray of light which travels towards a mirror?
3) A line which is drawn at right angles to the mirror surface at the point of incidence?
4)Name any one type of mirror which always form virtual image?

7)The part of eye which help to preserve its shape and protect it from external injuries?
8) The phenomenon through which judge depth?
9) The most sensitive part of eys?
1) wht is a periscope? state its working principle.
2) hw does ciliary muscle work
3) why does it tk sometime 2 see things in a dimly lit room whn we entr it frm a brightly lit area
pls experts fast
what is blind spot explain?????
what are optical aids and non optical aid???
write a short note on helen keller?
Does diffused reflection mean failure of the laws of reflection?
If the angle between the mirror and incident ray is 40 degree what will be the angle of incidence and angle of reflection?
two mirrors are kept perpendicular to each other . a ray strikes one mirror at an angle of 45 degree to the normal find the direction of the ray after reflection by the second mirror by drawing a ray diagram

how could i make model for human eye
function of electroscope
can a glass slab bend different coloured lights by different amounts?
The image formed on the retina persists for aboutof a second. This means that if you are shown still pictures of a moving object at a rate faster than 16 seconds, then the object will appear to be moving. This is because, the image of a picture stays on your retina for of a second and you will not be able to recognize the time taken to change these pictures.
Hello, I have not understood this para. Please explain......
what is the difference between image and shadow??????????
How to find the number of images formed between 2 mirrors placed at a certan angle ? Example ?
1)give two similarities between a human eye and a camera?

3)what kind of lens is used to correct short sighted eyes?
4)what do you understand by spectrum?
5) how is permanent blindness caused?
What are the differences between concave and convex lens?
What are the advantages and disadvantages of regular and irregular reflection?
