The sun emits energy in the form of electromagnetic waves at a rate of 3.9 x 10 W. This energy is produced by nuclear reactions deep in the sun's interior. ▾ Part A Find the intensity of electromagnetic radiation at the surface of the sun (radius r R-6.96 x 105 km). Ignore any scattering of the waves as they move radially outward from the center of the sun. Express your answer in watts per meter squared. I-6.4x10 W/m² Submit Previous Answers ✓ Correct Part B Find the radiation pressure on an absorbing object at the surface of the sun. Express your answer in pascals. Prad 0.21 Pa ✓ Correct Part C Previous Answers Find the intensity of electromagnetic radiation at rR/2, in the sun's interior. Express your answer in watts per meter squared.

Electromagnetic Waves

Electromagnetic waves are waves that consist of magnetic field and electric field components perpendicular to each other. These field components are also perpendicular to the direction of propagation of the wave.
