CONCEPT:

• Wavelength (λ): ​The minimum distance of separation between two particles that are in the same phase is called a wavelength.

EXPLANATION:

• From the definition, it is clear that wavelength is a distance.
• So its unit will be the same as the unit of length.
• Hence unit of wavelength is meter.
• So the correct answer is option 1.
