hope this will help u
Explanation:
Radiation = The emission of energy as electromagnetic wave or as moving subatomic particles , especially high energy particles which called ionization.
Conduction = The process by which heat or electricity is directly transmitted through the material of a substance when there is a difference of temperature or of electrical potential between adjoining region , without movement of material.
