Question

Can you please not only answer this but thoroughly explain how you got this - I am struggling

Which of these describe a principal ray for a concave mirror? (Select all that apply.) An incoming ray that is parallel to the optical axis will reflect as though it came from the focal point An incoming ray that comes from the direction of the focal point will reflect parallel to the optical axis An incoming ray that reflects off the mirror at the optical axis will reflect at the same angle from the optical axis (but on the opposite side of the optical axis) An incoming ray parallel to the optical axis will reflect through the focal point An incoming ray that passes through the focal point will reflect parallel to the optical axis An incoming ray that goes through the focal point will reflect back through the focal point Question 2 A kitten is in front of a concave mirror, outside its focal point. We can say that every ray that leaves the tip of one of its whiskers (and makes it to the mirror) must O must reflect through the focal point O must reflect through the optical axis at the focal point must reflect through the optical axis at the location of the image must reflect parallel to the optical axis reflect through the image of the tip of the whisker Question 3 You are looking in a mirror and see yourself upright and smaller than you would expect to see yourself. You are most likely looking in a: concave mirror (you are inside f) plane mirror concave mirror (you are outside f) convex mirror There is no mirror that would create this situation.

Answer 1

1. An incoming ray that is parallel to optical axis will reflect as though it came from focal point.

An incoming ray that comes from the direction of focal point will reflect parallel to optical axis.

An incoming ray that reflects off the optical axis at will reflect at the same angle from the optical axis (but in the opposite side of optical axis.).

An incoming ray parallel to optical axis will reflect throught the focal point.

An incoming ray that passes through the focal point will reflect parallel to optical axis

2. Must reflect through the optical axis at the focal point

Must reflect through the image of the tip of the whisker.

3. Convex mirror

Because only convex mirror make the Inverted and small image. Other mirror forms either Inverted or large images.

Question 1 and 2 are just laws of refraction.
