Two Nearly Equal Wavelengths of Light Are Incident on an N

question 66

Multiple Choice

Two nearly equal wavelengths of light are incident on an N slit grating.The two wavelengths are not resolvable.When N is increased they become resolvable.This is because:

• A)more light gets through the grating
• B)the lines get more intense
• C)the entire pattern spreads out
• D)there are more orders present
• E)the lines become more narrow
