Light has mass since it has energy.
Energy depends on the wavelength/frequency.
Einstein and Planck get credit for working this out.
Using red light of wavelength 650nm travelling in a vacuum we get a mass of 3.4x10^-36 kg. The weight depends on the gravity, but on Earth that would weigh roughly 3.332x10-35 N.
No, light year per hour is not a standard measure of speed. A light year is a measure of distance, not time. It represents the distance that light travels in one year.
A light year is actually a measure of distance. it's the distance that light travels in one earth-year. A year is a measurement of time equal to the amount of time that it takes the earth to go around the sun once.
A light year is the distance light travels in one year, equivalent to about 9.5 trillion kilometers (5.9 trillion miles). It is used as a unit of measurement in astronomy to describe vast distances in space.
A light year is a unit of distance, not a physical quantity. It represents the distance that light travels in one year in a vacuum.
The average weight of a 12-year-old's brain is around 3 pounds, which is roughly the same weight as an adult human brain.
