Question

question 2 (multiple choice worth 1 points)
(05.04 lc)
complete the following:
when light is incident parallel to the principal axis and then strikes a converging lens,
○ the light will remain parallel after refracting through the lens
○ the light will remail parallel after refracting backwards from the lens
○ the light will refract through the focal point on the opposite side of the lens
○ the light will refract through the focal point on the same side as the object

question 3 (multiple choice worth 1 points)
(05 04 lc)
complete the following:
when light is incident through the focal point, and then strikes a converging mirror,
○ the light will reflect parallel to the principal axis
○ the light will reflect through the focal point
○ the light will pass through travel parallel to the principal axis
○ the light will pass through travel through the focal point

Explanation:

Question 2

For a converging lens, the property of light incident parallel to the principal axis is that it refracts through the focal point on the opposite side of the lens. The first option is wrong as light doesn't remain parallel. The second option is incorrect as it's about refracting backwards (not a standard behavior here). The fourth option is wrong because the focal point for refraction of parallel incident light is on the opposite side, not the same as the object.

For a converging mirror, when light is incident through the focal point, after reflection, it travels parallel to the principal axis. The second option is wrong as it doesn't reflect through the focal point. The third and fourth options are incorrect as light reflects (doesn't pass through) a mirror, and the direction is parallel to the principal axis, not through the focal point.

Answer:

C. the light will refract through the focal point on the opposite side of the lens
