Explanation Given Info: The power of laser A is 2.6 W and the diameter of the cylindrical laser beam is 2.6 mm . And uniform intensity distribution over the cross sections, the amplitude of electric field in laser B is 480 V / m . And uniform intensity distribution over the cross sections, The amplitude of the magnetic field in the laser C is 8.7 × 10 − 6 T And uniform intensity distribution over the cross sections, The diameter of the cylindrical beam is 1.8 mm and the force on totally reflected surface is 6.0 × 10 − 8 N . And uniform intensity distribution over the cross sections, The average energy density in the beam is 3.0 × 10 − 7 J / m 3 . And uniform intensity distribution over the cross sections. Formula to calculate the intensity of the beam is, I = P A (I) P is the power of laser A , A is the area of the laser A . Formula to calculate the area of the laser is, A = π d 2 4 d is the diameter of the cylindrical beam. Substitute 2.6 × 10 − 3 m for d , A = π ( 2.6 × 10 − 3 m ) 2 4 = 5.3066 × 10 − 6 m 2 Substitute 5.3066 × 10 − 6 m 2 for A and 2.6 W for P in (I) to find I , I = ( 2.6 W ) 5.3066 × 10 − 6 m 2 = 4.9 × 10 5 W / m 2 Thus, the intensity of the laser A is 4.9 × 10 5 W / m 2 . Formula to calculate the intensity of the electromagnetic wave is, I = 1 2 ε 0 c E max 2 ε 0 is the electric constant, c is the speed of the light in vacuum, E max is the maximum value of the electric field amplitude. Substitute 2.998 × 10 8 m / s for c , 8.854 × 10 − 12 C 2 / N ⋅ m 2 for ε 0 and 480 V / m for E max to find I , I = 1 2 ( 8.854 × 10 − 12 C 2 / N ⋅ m 2 ) ( 2.998 × 10 8 m / s ) ( 480 V / m ) 2 = 310 W / m 2 Thus, the intensity of the laser B is 310 W / m 2 . Formula to calculate the intensity of the electromagnetic wave is, I = 1 2 ε 0 c E max 2 (II) ε 0 is the electric constant, c is the speed of the light in vacuum, E max is the maximum value of the electric field amplitude. Formula to calculate the maximum value of the electric field amplitude as follows, E max = c B max c is the speed of the light in vacuum, B max is the maximum value of the magnetic field amplitude. Substitute c B max for E max in (II), I = 1 2 ε 0 c ( c B max ) 2 = 1 2 ε 0 c 3 B max 2 (III) Substitute 2.998 × 10 8 m / s for c , 8.854 × 10 − 12 C 2 / N ⋅ m 2 for ε 0 and 8.7 × 10 − 6 T for B max in (III) to find I , I = 1 2 ( 8
