Optics
when a lighted candle is placed infront of a thick plane glass mirror, several images can be seen, but the second image is the brightest why?
Optics
a prism with refracting angle 60 degrees has a refractive index 1.52 for red and 1.6 for violet light. a parallel beam of white light is incident on 1 face at an angle of incidence which gives minimum deviation for red light. What is the length of spectrum if it is focused on a screen by a lens of focal length 100 cm.?
Optics
newton's rings using monochromatic light. If radius of curvature of lens is 70 cm and diameter of 10th dark ring is 0.4062 cm find wavelength of monochromatic light used
Optics
a concave mirror produces a three times magnified real image of an object placed at 10cm in front of it.where is the image located?
Optics
a limited region taken on a wavefront which is far away from the source as?
Optics
a diverging lens with a focal length -42.0cm forms a virtual image 6.0mm tall, 16cm to the right of the lens. find [a] the position and size of object [b] is the image erect or inverted [c] are the object and the image on same side or on opposite sides of the lens?
