The correct Answer is:
To determine the unit of measurement for wavelength, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Concept of Wavelength**: - Wavelength refers to the distance between two consecutive points in a wave that are in phase (e.g., crest to crest or trough to trough). 2. **Identify the Relevant Term**: - The term "wavelength" contains the word "length," which indicates that it is a measurement related to distance. 3. **Consider the Measurement Units**: - The question provides four options: - kg (kilogram) - a unit of mass - s (second) - a unit of time - L (liter) - a unit of volume - m (meter) - a unit of length 4. **Eliminate Incorrect Options**: - Since wavelength is a measure of length, we can eliminate kg, s, and L as they do not pertain to length: - kg is for mass - s is for time - L is for volume 5. **Select the Correct Option**: - The only option left that measures length is m (meter). Therefore, wavelength is measured in meters. ### Final Answer: Wavelength is measured in meters (m). ---
