Magnification of mirror is given by:
m=1/p+q
m=p/q
m=pxq
m=q/p
A data storage device is:
CPU
Printer
Hard disk
Monitor
The index of refraction depends on:
the image distance
The focal length
The speed of light
The object distance
To see from submarine the ship at the surface of water , we use:
Prism
Microscope
Telescope
Peri scope
In a convex mirror the size of the image:
Is smaller than the size of the object
Is equal to the size of the object
Depends upon the position of the object
Is greater than the size of the object
The mirror whose inner surface is reflecting is called:
Concave mirror
Lens
Miroor
Convex mirror
Snell’ law is:
n = sin<x/sin <r
n=sin <i/sin<r
<i/<r
n = sin <r/sin<i
Snell’s law is stated as:
sin r / sin i = n2/n1
sin i / sin r = n2/n1
Sin i / sin r = n1/n2
sin r / sin i = 2n2/n1
The totally reflectiing prism one angle is of:
120o
180o
45o
90o
The distance of image from mirror is represented by:
m
q
p
F
