Question

предмет находится на расстоянии 40 см от плоского зеркала. Каково будет расстояние между ним и его изображением, если предмет удалить от зеркала еще на 25 см?

Answer 1

Calculation of the Distance between the Object and its Image

To calculate the distance between the object and its image when the object is moved further away from the mirror, we can use the mirror formula:

1/f = 1/d_o + 1/d_i

Where: - f is the focal length of the mirror, - d_o is the distance between the object and the mirror, and - d_i is the distance between the image and the mirror.

In this case, the object is initially located 40 cm away from the mirror, and it is moved an additional 25 cm away from the mirror. We need to find the new distance between the object and its image.

Let's calculate it step by step:

1. Calculate the focal length of the mirror: - We don't have information about the type of mirror used, so we cannot directly calculate the focal length. We need this information to proceed with the calculation.

2. Calculate the initial distance between the object and the image: - Since the object is located 40 cm away from the mirror, the initial distance between the object and the image is also 40 cm.

3. Calculate the new distance between the object and the image: - To calculate the new distance, we need to know the focal length of the mirror.

Unfortunately, the search results provided by You.com do not contain the necessary information to calculate the focal length of the mirror. Therefore, we cannot provide a specific answer to the question at this time.
