ECZ PAST PAPERS FOR GRADE 12 - Science Paper 1 2019 Internal Part 1.

[@THEDMSONLINESCHOOL]

Hello guys, take note for question 13 section A, i made a big mistake in calculating the refractive index, i didn't notice that i got a wrong angle for the angle of refraction. I was supposed to substract 63 from 90 to get 27. So the correct answer is 1.92, which is D.

[@RachelLungu-t5h]

Why were we subtracting sir?

[@nightjoker6012]

Thank you very much I had challenges answering science papers but your help am getting first distinction next year 2023.keep up the good work

[@THEDMSONLINESCHOOL]

You are welcome

[@THEDMSONLINESCHOOL]

Thanks for letting us know ❤️ ❤️ ❤️. We really appreciate your feedback.

[@sakalapeter3029]

Amen

[@dorcaschiwanda1054]

This is wonderfully done. But 13. The angle of refraction should have been between the normal and the ray. Thus, I think you should have subtracted 63 from 90 sir. But Job well done

[@KachanaMakandauko-ge1gg]

On question 13 angle of refraction it's supposed to be 90- 63=27 that's the angle of reflection reason being it's always from the normal.

[@THEDMSONLINESCHOOL]

Thanks for your feedback, you might be correct because I also make mistakes.

[@sakalapeter3029]

Am very much glad with your explanation Sir!

[@THEDMSONLINESCHOOL]

[@THEDMSONLINESCHOOL]

Thank you so much.

[@chimwemwemulenga3099]

There was an error on Question A13, I think you’re supposed to subtract 63 from 90 in order for you to find the angle of refraction.

[@PaulMwale-fe3xk]

Sorry sir. On question 13 there's no answer on the given options. 63 is not the angle of refraction. The angle of refraction is the angle between the normal and the refracted ray. The examiners made a mistake on that one

[@pethiaschanda7938]

Thank you sir 🙏🙏

[@sakalapeter3029]

You're welcome!

[@anoldsimakwati702]

So good sir

[@kingjahseh4203]

What about section B?

[@marymutale1866]

4) 1.67 how did you get it?

[@THEDMSONLINESCHOOL]

I did explain, it's maybe the language they used which is tricking you. One sixth of 10 means (1/6)×10 = 10/6 = 1.67, rounded off to 2 decimal places. I hope you have gotten something. ❤️❤️❤️
