Aparticular wave can be described as transverse and self-propagating. what type of wave could it be?
a sound wave
a seismic wave
an ocean wave
a radio wave

A radio wave

Explanation:

Self propagating waves are those type of waves in which wave will induce the effect of by its own components.

One of the best example for this is Electromagnetic waves.

In electromagnetic waves electric field components and magnetic field components will oscillate perpendicular to each other and they both are perpendicular to the direction of propagation of wave also.

So here the disturbance due to electric field and magnetic field is since perpendicular to wave propagation so it is known as transverse wave.

So here we can say that correct answer must be an electromagnetic type of wave

so it must be

A Radio Wave.

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

i don't know that i agree with that but what's the question ?
