Wave Optics question

2024 · 31 Jan · Shift 1 · Q90

JEE MainPhysicsWave OpticsNumerical+4 / −1
Two waves of intensity ratio 1:91: 91:9 cross each other at a point. The resultant intensities at that point, when (a) Waves are incoherent is I1I_1I1​(b) Waves are coherent is I2I_2I2​ and differ in phase by 60∘60^{\circ}60∘. If I1I2=10x\frac{I_1}{I_2}=\frac{10}{x}I2​I1​​=x10​ then x=‾x=\underline{\hspace{2cm}}x=​.
