Arranging Lenses in Increasing Magnitude
This question requires us to understand the relationship between different units of length and how they relate to the size of a lens.
Understanding the Units:
- Kilometer (km): The largest unit, representing 1000 meters.
- Meter (m): A standard unit of length.
- Centimeter (cm): A smaller unit, representing 1/100th of a meter.
- Millimeter (mm): The smallest unit, representing 1/1000th of a meter.
Arranging the Lenses:
Based on the above information, we can arrange the lenses in increasing order of magnitude:
- 1 mm (smallest)
- 1 cm
- 1 m
- 1 km (largest)
Explanation:
The size of a lens is directly related to its focal length. A shorter focal length means a smaller lens, while a longer focal length means a larger lens. Therefore, the lens with a 1 mm focal length is the smallest, followed by 1 cm, 1 m, and finally 1 km.
Important Note:
While it is technically possible to have lenses with focal lengths in kilometers, they are incredibly large and not commonly used in practical applications.
