Answer:
Each part of the spectrum has a different range of wavelengths (which correspond to frequency, color, and energy) at which you can find it.
In a longitudinal wave, the motion of the medium is parallel to the direction of the wave.
A transverse wave is a wave in which the motion of the medium is a right angles to the direction of the wave.
Answer:
Explanation:
1. A solenoid is a coil which has many turns. When current flows through a solenoid, it behaves as an electromagnet. This behavior is due to the magnetic effect of an electric current thereby causing one end of the solenoid to behave as a north pole, while the other end as a south pole.The external influence of the earth's magnetism constrains the solenoid to come to rest in a N-S position just like a bar magnet.
2. The magnetic compass can be used to trace the alignments or patterns of the magnetic field around a current carrying wire. When current flows in a wire, it induces magnetic field around it. If the value of current is increased, the strength of the magnetic field would increase and vice versa. This shows that current is proportional to the strength of the magnetic field produced around the wire. Thus this causes a deflection of the compass appropriately, as the deflection of the compass is proportional to the strength of the field.
I think b but I’m not completely sure
