Answer:
A device designed to transmit electromagnetic waves through the air should be developed.
So for D you have to find energy right
from c you get wavelength Lambda
so on D use this
E = Hc / lambda
c is given 1.5 x 10 ^20
h = 6.624 x 10^-34
and then you get answer for energy
Answer: Conduction
Explanation:
Conduction means the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
Meaning that its when an object touches another object and heat gets transferred.
