Solution:The de-Broglie wavelength is given byλ=hmv We know that root mean square velocity ofa gas particles at a given temperature is given by 12mv2=32kT or V=3kTm or mv=3mkT Substituting the value ofmv from eq. (2) ill eq. (1), u.e get λ=h(3mkT) So λHλHe=mHe⋅THemHTH=(4)(273+127)(2)(273+27)=83 Related content Test your English Vocabulary CUET Exam Dates 2024 – Application Form, Fees, Eligibility CBSE Class 12 IP Answer Key 2024,Informatics Practices Paper Solution For SET 1, 2, 3, 4 CUET UG Cut Off 2024, Category, Universities and Colleges Wise Expected Cut Off Modal Verbs Helping Verbs Letter To Your Friend About Your School Trip Action Verbs CUET 2024 – List of Colleges and Participating Universities Accepting CUET Exam Score SRMJEEE Online Test Series – Practice Papers
