light have mass or not??..if u say yes/or,no.,then there is one comment that.....if u say no then how its reflect to any shinning object ,because without mass ,i think its impossible to reflect and whatever,...and if u say yes then in the presence of sun or absent of sun may be there is little difference between thier weight,but there is no any difference of any particular(fixed) weight...so I just stuck in this compliment...and I really want to know what's the real and perfect answer. ..

okay so u want to know light has mass or not right. okay lets try to explain it.

now we know a relation from einstein's theory of relativity which is

m'=m/√1-v^2/c^2

now if put v= c(speed of light)

then mass will tend to infinity

hope you have understood

thanks for asking

SSrajput: truly ,i couldn't understand...what u said mass tends to infinity,so what..what happens if mass tends to infinity?.. actually i dont have information that how mass goes tends to infinity,and whats will be the results...clear me

Vanshsharma420: come on bro kisi ka bhi mass infinity nahi ho skta right so 2 poss

Vanshsharma420: possibilty is photon is massless

SSrajput: . may be u r r8 .but u know photon jab pocket ke shape me aata h to after striking ye phoot kar ke alag hota h.....so bina mass ka agar rahenga to phootenga kaise....mai apna baat apko aacha se nai samjha pa raha hu ..sorry but u can understand what i mean to say...word me mat jaiye bhawna me jaiye ..ki kya kehna chata hu mai

Vanshsharma420: ok bro lets move on to quantum world. see bro hamare universe ek feild hai called higgs boson feild jo bhi us feild se jitna takrata hai uska mass utna hi ho jata hai photon bahut kam takrata hai so uska mass negligible hota hai. note the word negligible

SSrajput: due to few amount hmlog usko neglate kar dete h na?..kk..thank u..

Vanshsharma420: yes

Answer:hii ....here is your answer.......

according to this formula..........we know that radius of the earth is inversely proportional to the acceleration due to gravity if radius increase acceleration due to gravity decrease and if radius decrease is acceleration due to gravity is increased .......

if any doubt please comment.......
