-
Working with wavelength scales in spectroscopy, astronomy, radar, and ultrasonic sensor design
Tips & Best Practices
-
Ensure you input wavelength values in nanometres for accurate conversion
-
Use the converted centimetre values when dealing with antenna dimensions or waveguides
-
Take wave speed changes in different media into account if working outside of vacuum or air
Limitations
-
Conversion precision may decrease when converting very small optical wavelengths to much larger unit scales
-
Assumes wave propagation in vacuum or air; wavelength may vary in different media due to wave speed differences
Frequently Asked Questions
-
What is the formula to convert wavelength from nanometres to centimetres?
-
The conversion formula is 1 nm equals 1e-7 cm, so multiply the nanometre value by 1e-7 to get centimetres.
-
Why convert wavelength from nanometres to centimetres?
-
Converting to centimetres helps apply wavelength measurements from optical frequencies to antenna design, radar, and ultrasonic systems.
-
Does the tool consider different media for wavelength conversion?
-
The conversion assumes electromagnetic waves in vacuum or air; variations in wave speed in other media are not accounted for.
Key Terminology
-
Wavelength in nanometres [nm]
-
Distance between successive peaks of an electromagnetic wave measured in nanometres, commonly used for optical and near-infrared radiation.
-
Wavelength in centimetres [cm]
-
Distance between successive identical points of a periodic wave expressed in centimetres, often used in antenna and microwave engineering.
-
Frequency–wavelength relationship
-
For electromagnetic waves in vacuum, wavelength and frequency are inversely related by the formula c = λ·f, where c is the speed of light.
