What is the mass of a photon?

Very interesting 🤔

A photon is a light particle and light doesn't have mass

it is not entirely correct. we identify mass and energy as equivalent. We cannot measure the mass, but E=hv, v= frequency, E= mc^2. So a photon acts as if it has a mass of m=hv/c^2 That's how we treat it in physics.

Cartrell Holt, I wonder too,my personal opinion is many researchers and schoolers have debated such topic before the likes Terence Howard trying to show the world how this calculations,numbers,theories & studies have been misleading. Take an example of sunglasses to prevent UV light from the sun, apparently black Africans need it more than any other race & I'm not trying to be racist but truth is blacks are not taught this things.

Tom, Thanks for the clarification.

Ethan, Thank you!

Cartrell Holt, Go it

Trick question 🙋 so how many got it right I wonder?

Is it alive that it does not have mass just like everyone else.I still no and I am just 11.

how am I supposed to know that I'm only 12 years old dude

Knew I should have payed attention to Young Sheldon 😊
