Electromagnetic Waves question

2024 · 27 Jan · Shift 2 · Q76

JEE MainPhysicsElectromagnetic WavesMCQ+4 / −1
An object is placed in a medium of refractive index 3 . An electromagnetic wave of intensity 6×108 W/m26 \times 10^8 \mathrm{~W} / \mathrm{m}^26×108 W/m2 falls normally on the object and it is absorbed completely. The radiation pressure on the object would be (speed of light in free space =3×108 m/s=3 \times 10^8 \mathrm{~m} / \mathrm{s}=3×108 m/s ) :
  1. A
    6 Nm−26 \mathrm{~Nm}^{-2}6 Nm−2
  2. B
    36 Nm−236 \mathrm{~Nm}^{-2}36 Nm−2
  3. C
    18 Nm−218 \mathrm{~Nm}^{-2}18 Nm−2
  4. D
    2 Nm−22 \mathrm{~Nm}^{-2}2 Nm−2
