Question 2 of 7
Assertion (A): Sunlight reaches us without dispersion in the form of white light and not as its components.
Reason (R): Dispersion takes place due to variation of refractive index for different wavelengths but in vacuum the speed of light is independent of wavelength and hence vacuum is a non-dispersive medium.

Question 3 of 7
Assertion (A): Eye lens has the ability to focus clearly on the retina by adjusting its focal length.
Reason (R): This phenomenon is known as the power of accommodation.

Question 4 of 7
Assertion (A): Concave lens is used to correct myopia or short- sightedness.
Reason (R): A concave lens of suitable focal length diverges the parallel rays from the distant objects as if they are coming from the far point of the myopic eye. This helps the eye lens to form a clear image at the retina.

Question 5 of 7
Assertion (A): A hypermetropic person prefers to remove his spectacles, while driving.
Reason (R): When a hypermetropic person wearing the spectacles looks at a distant object, the parallel rays from the distant object converge in front of the retina. The image thus appears blurred.

Question 6 of 7
Assertion (A): In case of a rainbow, light at the inner surface of the water drop gets internally reflected.
Reason (R): The angle between the refracted ray and normal to the drop surface is greater than the critical angle.

Question 7 of 7
Assertion (A): A white light on passing through prism splits into its component colours as such that the red light emerges nearest to the base of the prism.
Reason (R): Wavelength of red light is more than other component colours and hence, red light deviates least.
