Question
The angle between two mirrors is 0 degrees. How many images would they produce?
- 1
- 2
- 5
- Infinitely many
Hint:
Parallel mirrors are used to create an illusion.
The correct answer is: Infinitely many
- If the two mirrors are aligned at 0 degrees to each other (that is, a parallel mirror system), there are an infinite number of images.
- All images are the result of images or images of images or images of images. The figure below shows multiple images of a parallel mirror system.
- Images I1 and I2 are primary images. Image I1 is the image resulting from the reflection of object O through mirror M1 and image I2 is the image resulting from the reflection of object O through mirror M2.
- Image I3 is an image of image I1 found by projecting image I1 onto mirror M2. Image I4 is an image of image I2. It is detected by mirroring image I2 onto mirror M1.
- This process continues indefinitely, generating an image from an infinite number of images spread to the right of mirror M2 and to the left of mirror M1.

What should a person do when dust enters their eyes?
The correct option is c)Wash your eyes using clean water.
Slight temporary visual impairment may occur. Once the dust is removed, the swelling and irritation of the eye is reduced and vision returns to normal. However, there is a possibility of infection due to bacteria contained in dust. Therefore we should immediately wash your eyes with cold water.
