Question

What is the range of wavelength of the spectrum of white light in $A^o$ ?

• A. $4000A^o$ to $5000A^o$
• B. $5000A^o$ to $6000A^o$
• C. $6000A^o$ to $8000A^o$
• D. All the above

Answer 1

Answer: (D)

All the above

The range of wavelength of visible light is approximately $4000-8000$$A^o$, with violet being at the lower end ($3800-4500$$A^o$) and red at the higher end ($6200-7500$ $A^o$).
