An electromagnetic wave is transporting energy in the negative y direction. at one point and one instant the magnetic field is in the positive x direction. the electric field at that point and instant is: why is (d) the answer? i thought it's (c)a) positive y directionb) negative y directionc) positive z directiond) negative z direction

negative Z direction

Explanation:

It is given that EM wave is travelling in negative y direction i.e. -

Magnetic Field is in positive x direction i.e.

We know that Electric field and magnetic field are perpendicular to each other and they are mutually perpendicular to direction of wave propagation.

Mathematically if Electric field is in negative z direction it will yield the direction of wave propagation

i think the correct answer from the choices listed above is option c. when the kinetic energy of particles in a liquid state decreases

explanation:

science is a systematic and logical approach to discovering how things in the universe work. true to this definition, science aims for measurable results through testing and analysis. science is based on fact, not opinion or preferences. the process of science is designed to challenge ideas through research.
