SciPy - Constants and Special Functions

How would you modify this code to calculate the wavelength in nanometers given photon energy in electronvolts?

from scipy.constants import c, planck, electron_volt
energy_ev = 2.5
energy_joule = energy_ev * electron_volt
wavelength = planck * c / energy_joule
print(wavelength)

ANo modification needed; code is correct

BMultiply wavelength by 1e9 to convert meters to nanometers before printing

CMultiply energy_ev by 1e9 before conversion

DDivide wavelength by 1e9 to convert meters to nanometers before printing

Step-by-Step Solution

Solution:

Step 1: Understand units of wavelength output
The calculation yields wavelength in meters.
Step 2: Convert meters to nanometers
Multiply meters by 1e9 to get nanometers.
Final Answer:
Multiply wavelength by 1e9 to convert meters to nanometers before printing -> Option B
Quick Check:
Convert meters to nm by multiplying by 1e9 [OK]

Quick Trick: Meters to nm: multiply by 1e9 [OK]
