State the rules of image formation by lenses.What is the nature (real or virtual), and size of the image formed by a convex lens when 1) the object is at 2F1 2) the object is placed between F1 and 2F1?
Can we consider water as a lens?
Can we make lens by usng water?
Please refer exercise question 1 of page 185.
In what way yhe word AMBULANCE is
How an electric bulb be considered as extented source of light and as point source of light ?
If the image distance is negetive then what will be its magnification?will it be v/u or -v/u
why does water appear colourless whereas atmosphere is blue in colour?
an object 6cm is placed18cm away from a concave mirror . the image formed is 12cm before the mirror . find f,R, H1,m.
my question is how v=-12. pls tell me.
TELLME ANY 20 USES OF CONCAVE$CONVEX MIRRORS????
how to produce current
If the velocity of light in a medium = 2.25 x 10^8 m/s, find the refractive index of that medium?
why is it said that snell's law fails when angle of incidence is 0
What is the principle of reversibility of light?
a light of wavelenghth 5000angstrom is incident on a glass slab, whose refractive index is 1.5. what will b the wavelength of incident light in glass
what is optical density????
sign convenctions in spherical mirror and lens (concave & convex)
