If light falls perpendicularly on a plane mirror, what will be the angle in which it will be reflected?

45° 90° 180° 360°

In the retina of the eye, the area having no sensory cells is called

Iris Blind spot Cornea Dark spot

We can see a non-luminous object when the light:

Emitted by the object falls on the eye. Is reflected from the object towards our eye. Completely passes through the object. Gets completely absorbed by the object.

25 m 2.5 cm 25 cm 2.5 m

Which of the following statements is correct regarding rods and cones in the human eye?

Cones are sensitive to dim light. Cones are sensitive to bright light. Rods are sensitive to bright light. Rods can sense color.

The angle between an incident ray and the plane mirror is 30 degree. The total angle between the incident ray and the reflected ray will be:

30° 60° 90° 120°

Boojho is doing his homework which is given by his teacher. Would you help him to choose the correct sentences?

The incident ray, the reflected ray and the normal, all lie in the same plane. The angle of reflection is always equal to the angle of incidence. If we change the angle of incidence, the angle of reflection will also change accordingly. All the above.
