You are given four sources of light each one providing a light of a single colour red, blue, green and yellow. Suppose the angle of refraction for a beam of yellow light corresponding to a particular angle of incidence at the interface of two media is 90. Which of the following statements is correct, if the source of yellow light is replaced with that of other lights without changing the angle of incidence?
A real image is formed when two or more
Select the odd one out w.r.t. the type of reflection of incident light
Regular reflection takes place when light is incident on:
Type of reflection in which images are formed and reflection occurs from a smooth surface like that of mirror is known as:
Irregular reflection occurs due to:
Moon is visible to us because:
When all the parallel rays reflected from a plane surface are parallel, the reflection is known as:
Which of the following can form image?
Mark the statement which is true for diffused reflection:
Why we are not able to see our image on a cardboard even though it reflects light?
Which of the following is /are type of reflection ?
When light is incident on a polished surface ___________ reflection takes place.
Which surfaces will reflects most of the light falling on them?
A bus driver is reversing his bus at a speed $8 m s^{-1}$. The rear view mirror of a bus is a plane mirror. The driver sees in his rear view mirror the image of a car parked behind his bus. The speed at which the image of the car appears to approach the driver will be
Diffused reflection
Irregular reflection obeys laws of reflection .
Reflection from a smooth surface is called __________ reflection.
