(Figure 1) shows the light intensity on a viewing screen behind a single slit of width a. The light's wavelength is λ.
Is lambda < a,λ = a, λ > a, or is it not possible to tell? Drag the terms on the left to the appropriate blanks on the right to complete the sentences.
w=2 Lλ / a
w=2 a λ / L
equal to
less than
w=2 La / λ
greater than
w=2aL / λ
The width of the central maximum in the intensity pattern for a single slit is given by _____
If λ≥a then w will be equal to or _____ 2L
It is obvious that w ≤ 2L, hence is λ _____ a.
