The transfer of heat that utilizes or occurs in the form of wave, would be B. Radiation. As heat, can be emitted in the form of waves which constitute or make up the electromagnetic spectrum, specifically these include UV Rays from the sun for instance.
Metals can form a sea of elections which causes them to be good conductors of energy
Answer:
51 dioptre
Explanation:
u = Object distance = 2 cm
v = Image distance = 1 m
f = Focal length
Lens Equation
![\frac{1}{f}=\frac{1}{u}+\frac{1}{v}\\\Rightarrow \frac{1}{f}=\frac{1}{0.02}+\frac{1}{1}\\\Rightarrow \frac{1}{f}=\frac{1.02}{0.02}\\\Rightarrow \frac{1}{f}=51\\\Rightarrow f=\frac{1}{51}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bf%7D%3D%5Cfrac%7B1%7D%7Bu%7D%2B%5Cfrac%7B1%7D%7Bv%7D%5C%5C%5CRightarrow%20%5Cfrac%7B1%7D%7Bf%7D%3D%5Cfrac%7B1%7D%7B0.02%7D%2B%5Cfrac%7B1%7D%7B1%7D%5C%5C%5CRightarrow%20%5Cfrac%7B1%7D%7Bf%7D%3D%5Cfrac%7B1.02%7D%7B0.02%7D%5C%5C%5CRightarrow%20%5Cfrac%7B1%7D%7Bf%7D%3D51%5C%5C%5CRightarrow%20f%3D%5Cfrac%7B1%7D%7B51%7D)
Power of lens
![P=\frac{1}{f}\\\Rightarrow P=\frac{1}{\frac{1}{51}}\\\Rightarrow P=51\ D](https://tex.z-dn.net/?f=P%3D%5Cfrac%7B1%7D%7Bf%7D%5C%5C%5CRightarrow%20P%3D%5Cfrac%7B1%7D%7B%5Cfrac%7B1%7D%7B51%7D%7D%5C%5C%5CRightarrow%20P%3D51%5C%20D)
Power of the eye lens is 51 dioptre.
I'd Say B :) Your Welcome LOL!!!!!
it is no longer and electromagnetic wave.
