[@kashibiko]

[@Cabbyiii]

[@aaryavsinha5947]

​@@CabbyiiiSame!

[@nivassikkandar7427]

[@sachchitsahay5968]

[@Vikramgaming2627]

Yeah true

[@RaiRajeswori]

That is from fnaf 4. I kind of half expected a jump scare to be there but luckily it wasn't there

[@Cabbyiii]

Ive been waiting to find fnaf in the wild since I was five lmao

[@vishwa-vhv]

amazing and very interesting class thanks byju's😍

[@ElonMusk-kw6fo]

9/10 Sir I have doubt in this question:- An incident ray makes an angle of 65 degree with the surface of a plane mirror. The angle of reflection in this case will be: 15° 25° 45° 90°

[@lavanyaarjun6282]

25degree answer

[@hemantkumarchauhan8048]

May be 25°

[@amitsangwan2219]

Answer is 25° because till the incident ray the distence was 65 degrees that means we want 25° more to reach the normal and then if you see the the angle of incidence is 25° then the Law of Reflection (angle i= angle ii) angle of reflection will be 25°.

[@shaaravshresth5001]

​​@@soul_slayer0hi , I am a 7th grader but can help youOut The 65 one is called the glancing angle which is angle of incident ray with miror but angle i is incident ray with normal Also normal makes 90deg with the mirror so the equation will be Glancing angle plus angle i =90degree 65+x=90 X=25 z Hope this helps 🎉 Power 🔋 🏴 of allenite 😊😊😊😊😊❤❤❤❤

[@Shreyansh_Patra]

Pura chapter ka video dekh liya aur ye esa phaltu question kyu puch rahe ho ?!? Mirror plane to incident ray is 65 degree so, incident angle = 90-65. So, Incident angle = 25 degree. As we know that incident angle = reflected angle. Then reflected angle = 25 degree

[@knowledgeandgamesofaadvikh568]

Sir incident ray, reflected ray and normal all lie in the same plane *at the point of incidence* . Is it correct sir??

[@satinderpal4729]

Yes beta

[@Awesome_editz190]

5:54 but sir ka head can

[@protwins7698]

10:30 then he say this just😂

[@sufiyaamber103]

Hello sir. Sir this question was easy but I am not able to understand what it means. Some standing in front of a plane mirror. The distance between Sam and his image is 10 m. How far is he standing from the mirror

[@Piyush_singh99]

The distance between Sam and his image is 10 m. So distance between Sam and mirror is 5 m. And the distance between mirror and Sam image is 5 m. So 5m + 5m =10m.... 🙂🙂

[@sufiyaamber103]

@@Piyush_singh99 Thanks for the explanation ☺

[@amitsangwan2219]

The distence between Sam and his image is 10 m then what you just have to do is do the half of 10 that is 10/2=5m Because they have asked us the distence between the Sam and the Plane Mirror not between the Sam and his image.

[@sufiyaamber103]

​@@amitsangwan2219 Thanks

[@Shreyansh_Patra]
