In a Young’s double slit experiment, the intensities at two points, for the path differences λ/4 and λ/3 (λ being the wavelength of light used) are I1 and I2 respectively. If I0 denotes the intensity produced  by each one of the individual slits, then I1+I2I0 = ___________.

# In a Young’s double slit experiment, the intensities at two points, for the path differences $\mathrm{\lambda }$/4 and $\mathrm{\lambda }$/3 ($\mathrm{\lambda }$ being the wavelength of light used) are I1 and I2 respectively. If I0 denotes the intensity produced  by each one of the individual slits, then $\frac{{\mathrm{I}}_{1}+{\mathrm{I}}_{2}}{{\mathrm{I}}_{0}}$ = ___________.

### Solution:

for
${\mathrm{I}}_{1}=4{\mathrm{I}}_{0}{\mathrm{cos}}^{2}\frac{\mathrm{\pi }}{4}=2{\mathrm{I}}_{0}$
for
$\therefore \frac{{\mathrm{I}}_{1}+{\mathrm{I}}_{2}}{{\mathrm{I}}_{0}}=\frac{3{\mathrm{I}}_{0}}{{\mathrm{I}}_{0}}=3$
