Question:
Using the figure. Find the relative luminosity of wavelength
(a) $480 \mathrm{~nm}$,
(b) $520 \mathrm{~nm}$,
(c) $580 \mathrm{~nm}$
(d) $600 \mathrm{~nm}$
Solution:
According to figure:
(a) Relatives luminosity of wavelength $480 \mathrm{~nm}$ is $0.14$
(b) Relatives luminosity of wavelength $520 \mathrm{~nm}$ is $0.68$
(c) Relatives luminosity of wavelength $580 \mathrm{~nm}$ is $0.92$
(d) Relative luminosity of wavelength $600 \mathrm{~nm}$ is $0.66$
