SciPy - Constants and Special Functions

Identify the error in this code snippet:

from scipy.constants import planck
energy = planck * 3e8 / 400
print(energy)

ASpeed of light value is incorrect

BPlanck constant is not imported correctly

CPrint statement syntax error

DWavelength should be in meters, not 400 (assumed nm)

Step-by-Step Solution

Solution:

Step 1: Check units of wavelength in energy calculation
Wavelength must be in meters for correct energy calculation. Here 400 is likely nanometers but used without conversion.
Step 2: Identify the error cause
Using 400 directly causes wrong energy value. It should be 400e-9 to convert nm to meters.
Final Answer:
Wavelength should be in meters, not 400 (assumed nm) -> Option D
Quick Check:
Unit conversion error = wavelength not in meters [OK]

Quick Trick: Always convert wavelength to meters before calculation [OK]
