Can we consider water as a lens?
Can we make lens by usng water?
Please refer exercise question 1 of page 185.
what causes atmospheric refraction of light ?, mention its two uses
What is the position of an image when object is placed at a distance of 20 cm from a concave mirror?
why does water appear colourless whereas atmosphere is blue in colour?
how to produce current
where will be the image formed if the object is kept horizontal?
i want to know all about -ve and +ve signs in mirrors and lenses?
HOW TO MAKE RAY DIAGRAM FOR CONCAVE AND CONVEX MIRROR .PLZZ.EXPLAIN IN DETAIL WITH DIAGRAMS.WHAT IS MEANT BY INFINITY?FOR WHAT V AND U STANDS?
investicate weather different light contain different energy
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.
why is the sky blue...???? (its not given in the book its just a doubt..)
at morning the sun is at maximum distance therefore it appears red.Then why the the star dont appear red it is also at larger distance?
1. A green book viewed through red glass will appear ______ ?? (green / black / red / magenta)
2. A red paper illuminated by green light appears ______??? (green / yellow / black / blue)
Choose correct option in both answers and please provide a good reason for your answer.
a doctor has a corrective lens of power +1.5d.find the focal length of the lens.is the prescribed lens of diverging or converging
what is optical density????
