Can we use convex lens in place of concave mirror??

[@vatsalrajagarwal3452]

#YouCanLearnAnything #Doubt
Sir, I have a doubt..
In 2:43 you gave example of dish tv antenna. In that example although the dish has shape just like concave mirror , but it is not a mirror , isn't it? So, how can we hive this example in concave mirror applications??
Plz reply

[@lonewolf2826]

It reflects the Electromagnetic waves or radio waves,, . There's different types of waves. You can learn in different chapter

[@pallavichauhan1017]

Thanku sir

[@princybhargav5342]

Sir m studying from s chand's book and in this book we have given that light waves does not travel through any material medium such as solid liquid or gas
And now as u talked about light in the form of radio waves coming from tower so sir myy ques is that through which medium these light waves are coming as they can not travel through any material medium ??

[@prateekrajput9133]

Light rays can travel through material medium ,if not than how light rays travel in air and reach to us from sun.

[@princybhargav5342]

M talking about waves not rays
Light rays are of two types
1. In the form of waves
2. In the form of particles
I think m clear now?

[@prateekrajput9133]

@@princybhargav5342 light wave are electromagnetic wave hence they can travel even in absence of any material medium and also through mayerial medium

[@prateekrajput9133]

@@princybhargav5342 shayad tumne ye padha hoga ki light wave electromagnetic wave hain isiliye light wave bina kisi material medium ki bhi travel kar sakti hain or tumne socha hoga ki iska matlab light wave material medium se travel nahi kar sakti

Sir agr hme sound or light ko diverge krna hai to hm concave ka place pe convex kyu nahi lelete

[@aparichit9728]

Le skte h

[@prateekrajput9133]

Kyuki convex mirror light rays ko sabhi direction me spread karta hai jabki concave mirror sirf ek particular direction me

[@HimanshuSharma-tq7oz]

Kyunki concave mirror one direction me converge karta hai infact a convex mirror does not does

[@ashwinirawandale-cv7rn]

Thx sir

[@vikramgupta4616]

Sir according to diagram light Ray should be on the same side of focus but in torch u did opposite here light rays are in opposite direction of focus

[@shrinarayansingh8890]

Because in this case the incident rays imerge from the focus and thus rays imerge from the focus

[@sunilshukla5028]

How??

Sir yeh nahi samjhee ki light rays vaapas chali jaa rahe he in kaise

In car headlight the concave mirror is behind the bulb or in front of the bulb
