Answer 2

Hii Akshay,

◆ Metre length is most accurate in terms of wavelength of light because -

• Wavelength of light is universally constant.
• It doesnt vary with surroundng conditions like temprature, pressure, etc.
• It can measured in any standard laboratory using Krypton.
• It would be same measured anywhere in the world.

Thanks for asking. Hope I was useful..
