a) Blue light with a wavelength of 475 nm is passed through a double slit with a separation of 22.6 µm. What is the maximum number of nodal lines visible in the entire pattern? (96) b) State two changes to the nodal pattern if red light was used instead of blue light. (fewer nodal lines, larger spacing between nodal lines)
