Explanation / Answer

here,

I0 = 750 W/m^2

a)

the intensity of light when passes through the first polarizer ,I1 = I0 /2

I1 = 375 W/m^2

b)

the intensity of light when passed through the seccond polarizer , I2 = I1 * ( cos(theta))^2

I2 = I1 * ( cos(45))^2

I2 = 375 * ( cos(45))^2

I2 = 187.5 W/m^2
