In a transformer, energy is carried from the primary coil to the secondary coil by magnetic field in the iron core.
To find the answer, we have to know more about the transformer.
<h3>
How transformer works?</h3>
- An item utilized in the transfer of electric energy is a transformer.
- AC current is used for transmission.
- It is frequently used to modify the supply voltage between circuits without altering the AC frequency.
- The fundamentals of mutual and electromagnetic induction govern how the transformer operates.
- Magnetic field through the primary coil changes when primary coil current varies. the iron core of the secondary coil likewise has a magnetic field.
- EMF is therefore generated in the secondary coil.
Thus, we can conclude that, in a transformer, energy is carried from the primary coil to the secondary coil by magnetic field in the iron core.

Answer:
The statement is true
Explanation:
The complete question is
Light bends when it changes the medium because the dielectric permittivity of the material makes the path more hard to penetrate
True or False
Solution
The given statement is true as it is the dielectric permittivity of the material which does not allow light to pass through it easily.
The medium decrease the amplitude of light and hence induces change in direction without altering its velocity or frequency.
Higher temperatures means more energy, and a solid phase means the particles are close together. This results in highly energized particles that bump into the particles close to them, who in turn bump into more particles.
