In the absence of atmosphere, the colour of sky is [ ] a) blue b) white c) red d) black 5. Presbyopia can be corrected by _______ lens [ ] a) convex b) concave c) bifocal d) cylindrical 6. The sun appears redish in colour at early morning and at sunset due to ______ of light [ ] a) dispersion b) refraction c) scattering d) none of these

Answer 1

Answer:

1. dispersion
2. reflection, dispersion and internal reflection
3. reflection
4. black
5. bifocal
6. scattering :-)

Answer 2

Answer:1 is refraction became when light passes through the plane mirror it I refracted than it forms other colours

2 is a what the light is first refracted the m dispersed the it is totally internally reflected and it moves from a less dense medium to a more dense medium

3isreflection because it is the bouncing back of light rays as they hit a shiny surface and move in another direction

4 is I think black because in presence of the atmosphere the blue colour particles are "weak" so they are pushed and that is why the sky appears blue but without atmosphereit may be black

5 is bifocal is the answer because first of all convex is for long sight

concave is for short sight

cylindrical is for old sight i think its bifocal no

5 is scattering I think us but atleast thank me please coz most OF these answers are correct
