ap n conversion kar k kia ha question ko lemme solve then i will tell you bit later

no the best option is C

dekhy 1ev =1.6 10^-19 j hota ha then 1MeV kitna hua 1 eV ko M (10^6) se multiply karo then 1.602 multiply 10^-13 J aay ga ab ye energy joule me aa gai ha ab then simply apply formula E =hf rearrange f=E\h put values 1.6multiply 10^-13 \6.63multiply 10^-34 then answer is approximately 2.48 multiply 10 ^20 Hz

But unhon ny wavelength 1KEV ki di hai and f 1MEV ki mangi hai to sabse pehly frequency of 1KEV nhi nikalny Gy?! Then ratio sy solve

Kiuky mainy AISA Kiya hai and exactly D option ban rhi and mujhe kiu masla bhi ni smjh aarha calculation mai😭

Ap ny kis method kiye aap bhejdo

Khola Khalid · 2026-05-26T18:17:52.836Z

ap dekhy uno n ye to nhi kha ha k is photon ki itni ha to is photon ki M eV me kitni ho gi uno n simple 1 M eV ki pouchi ha to sab se phly simply ap isy joule me convert karo then simple E =hf waly formula se frequency nikal lo it is that simple

key me kia ha is ka answer
