What are the units of magnification?Select one:a.m2b.mc.No units.d.m-1e.m-2Clear my choice

Breakdown of the Problem

1. Identify what magnification refers to in optics.
2. Analyze the units provided as options.

Relevant Concepts

Magnification is a dimensionless quantity that describes how much larger an image is compared to the actual object. It can be represented as:

$\text{Magnification} (M) = \frac{\text{height of image}}{\text{height of object}}$

Analysis and Detail

1. Since magnification is a ratio of two lengths (image height to object height), it effectively cancels out the units, making it dimensionless.
2. The options presented are:
   • a. m² (square meters)
   • b. mc (not standard)
   • c. No units (dimensionless)
   • d. m⁻¹ (inverse meters)
   • e. m⁻² (inverse square meters)

Verify and Summarize

Given that magnification is a ratio of two lengths and does not possess any units, the correct answer must be "No units".

Final Answer

c. No units.
