i. When a ray of light refracts from a material with a lower index of refraction

Question

i. When a ray of light refracts from a material with a lower index of refraction to a higher index of refraction the ray bends away from the normal. ii. An object at infinity will always form an image at the focal point iii. Hyperopia (far-sightedness) is corrected using a converging corrective lens iv. Rayleigh's Criteria implies that finer resolution can be gained if larger lenses are used (all else being equal V. The "wave nature" of electrons in an interference experiment will be more apparent when the electrons are moving slowly. vi. The mass of a stable nucleus containing Z protons and N neutrons is always smaller than the mass of Z individual protons and N individual neutrons.

Explanation / Answer

i. False.

bends towards the normal.

as refraction angle will be less than incident angle.

ii. True.

because rays from infinity can be considered as parallel to principal axis so they will meet at focal point.

iii. this is corrected using concave lens Or diverginglens.

False

iv. True

v. False

vi. True.

becuse mass difference results in binding energy of nucleous.
