If photons are massless then how can it possess momentum and put force on other objects having mass??

The light ray coming from Sun have momentum though light is made up of massless particles which are photons...
Momentum is a effect...So we observe the momentum ( effect) of light when it incident on our hand during day time , it feels hot...This is really a new concept when we have momentum without a mass...Which is nothing just beginning of modern physics...or qunatum mechanics...nothing...
According to De' Broglie wavelenthg we have ,
Lambda = h / mv = h /p ----(i)
where
Lambda = De'Broglies Wavelength
h = planck's constant
mv = momentum = p
From relation (i) , we have
p = h / Lambda
=> Momentum = planck's Constant / De' Broglie wavelength ---(ii)
Here From equation (ii) we can see that There is no mass...but we still have momentum....Light have wavelength So it must have momentum according to relation (ii)...
Hope this help....
