The medical precept underlying the operation of fibre optics is the precept of general inner mirrored image through which mild alerts may be transmitted from one vicinity to some other with a negligible lack of energy.

 

(7bi)

Core: The middle is the mild transmission location of the fibre, both glass or plastic cladding. The characteristic of the cladding is to offer a decrease refractive index on the middle interface a good way to reason mirrored image withinside the middle a good way to permit mild waves transmitted thru the fibre.

 

 

(7bii)

Cladding: It features as a machine that offers a clean refractive index on the middle interface a good way to reason mirrored image withinside the middle in order that mild waves are transmitted thru the fibre.

Tips to Pass WAEC 2022 Physics Questions

1. Be Positive in Your Thought

It is apparent that till your mind-set is nice, your lifestyles will now no longer be nice. As you put together for WAEC 2022, you have to expand a nice mind-set closer to your fate. Don’t say, “WAEC Physics may be very difficult I don’t understand whether or not I will byskip” and don’t consider all and sundry that announces you can not byskip WAEC 2022 Physics to your very own.

 

Have the mentality, “If others exceeded WAEC 2022 Physics withinside the beyond, then I can be like them. Refuse to be recognized with failure or people who failed withinside the beyond.

 

Even if this year’s WAEC Exam isn’t your first time, it doesn’t imply which you can not byskip WAEC 2022 Physics this time around. Sit for maths 2022/2023 with a elegant mind-set. Nothing will make you fail WAEC 2022. Until your mind-set is nice, your lifestyles will now no longer be nice.

 

2. Be Mindful of the Friends You Keep

If you’re sincerely critical approximately passing WAEC 2022 Physics, attempt to keep away from terrible companies. They will discourage and have interaction you in sports on the way to now no longer decorate your success. Remember that their mind-set might not correspond to yours.

 

three. Target High
