A spider hangs by its string at an eye level 20 cm in front of the plane mirror. You are behind the spider, 50 cm from the mirror. What is the distance betwen your eye and the image of the spider in the miror?
The spider's image is 20 m behind the mirror. Add 50 cm (your eye-mirror distance) to that.
To find the distance between your eye and the image of the spider in the mirror, we need to calculate the total distance traveled by the light from the spider to your eye.
First, let's determine the distance between the spider and the mirror. We are given that the spider hangs 20 cm in front of the mirror.
Next, let's consider the distance between your eye and the mirror. We are given that you are positioned 50 cm away from the mirror.
So, the light travels a total distance of 20 cm (from the spider to the mirror) + 50 cm (from the mirror to your eye) = 70 cm.
Therefore, the distance between your eye and the image of the spider in the mirror is 70 cm.
