Question:medium
Light of wavelength 5000 \r{A is incident normally on a slit of width $2.5 \times 10^{-4}$ cm. The angular position of second minimum from the central maximum is}
Light of wavelength 5000 \r{A is incident normally on a slit of width $2.5 \times 10^{-4}$ cm. The angular position of second minimum from the central maximum is}
Show Hint
Be extremely careful with powers of 10! Always convert everything to cm or meters before starting. A common error is mixing Angstroms ($10^{-10}$ m) with centimeters ($10^{-2}$ m) without proper adjustment.
