A. Definition of Joules and nm Wavelength
The joule (J) is the unit of energy in the International System of Units (SI). It is defined as the work done by a one newton force acting over a one meter distance. On the other hand, the nanometer (nm) is a unit of length equal to one billionth of a meter. In physics, it is commonly used to describe electromagnetic waves’ wavelength.
B. Importance and Application of Energy Conversion
Energy conversion occurs in various processes and is essential to understand and measure. Converting energy from joules to nm wavelength helps scientists and engineers analyze and interpret data received from different energy sources, such as light and heat.
Ⅱ. Conversion Formula
A. Explanation of the Relationship between Joules and nm Wavelength
The conversion formula between joules and nm wavelength is derived from the relationship between energy and the frequency of electromagnetic waves. According to the equation E = hf, where E is energy, h is Planck’s constant, and f is frequency, the wavelength can be determined using the equation c = λf, where c is the speed of light and λ is the wavelength. Combining both equations, we get λ = c / f.
B. Mathematical Formula for Conversion
To convert joules to nm wavelength, we can use the formula λ (nm) = 1,240 / E (J), where λ is the wavelength in nanometers and E is the energy in joules. This formula is derived by substituting the speed of light value of approximately 3.0 × 10^8 m/s into the equation.
Ⅲ. Example Calculation
A. Given Value in Joules
Let’s assume we have an energy value of 500 joules.
B. Step-by-Step Calculation Process
1. Apply the conversion formula: λ (nm) = 1,240 / E (J).
2. Substitute the given value: λ (nm) = 1,240 / 500.
3. Calculate: λ (nm) = 2.48 nm.
Ⅳ. Significance of nm Wavelength
A. Explanation of Nanometer (nm) as a Unit of Measurement
