1) A person 1 m in front of a plane mirror seems to be m away from his image 2) if you touch your ear with the right hand in front of a plane mirror it will be seen in the mirror that your right ear is touched with
3) the size of the pupil becomes when you see in dim light
4) night birds have cones than Rods in their eyes .

please help me with this physics homework ಥ_ಥ

Here's the correct choices ~

1. A person 1 m in front of a plane mirror seems to be 1 m away from his image

because the distance of object and its image from a plane mirror is always the same ~

2. if you touch your left ear with the right hand in front of a plane mirror it will be seen in the mirror that your right ear is touched with left hand

that's because mirror has the property of lateral inversion ~

3. the size of the pupil becomes larger when you see in dim light.

the reason for that is the pupil accommodate according to get the required amount of light for sight. so when it's little dim pupil become large in order to gain more light.

4. Night birds have less cones than rods in their eyes.

that's because cones are sensitive to bright light and won't work properly at night, whereas rods are sensitive to dim light and good at night time making it more suitable at night. therefore the night birds have more Rods than cones.
