Yes, it has a mass - though the mass is quite small. As far as I know, the neutrino has not been found to have smaller parts.

What particle have mass of lamu?

The tau neutrino has mass and is denoted with the symbol μ.


What particles the one with the least mass is the electron proton neutron or neutrino?

Neutrinos, but their mass is very, very small.


How do neutrinos differ from photon?

A photon is a unit of light and has a mass of 0 where is a Neutrino has a small but nonzero mass. Neutrino's are similar to electrons in most regards, except neutrino's have no charge. Where photon's travel at the speed of light neutrino's come close but do not.


What subatomic particles have a mass of 0?

The photon. This refers to the "rest mass"; since the photon has energy, it also has an associated mass. But the "rest mass" or "invariant mass" is zero.


How big is a Neutrino?

A neutrino is an elementary particle and is considered to be nearly massless. Their rest mass is still not well determined, but it is known to be very small, less than 0.12 eV. In comparison, the mass of an electron is about 511,000 eV.


How can neutrino oscillation explain the solar neutrino problem?

The solar neutrino problem relates to the discrepancy between the proportions of the different flavours of neutrinos emitted by the sun in the theoretical model as opposed to experimental measurements. Whilst the sun primarily emitts electron neutrinos, neutrino observatories such as SNO+ detected neutrinos in roughly equal proportions of the three flavours; furthermore the quantity of electron neutrinos detected was less than the theoretically predicted value. Both of these can be explained by neutrino oscillation - in which the neutrinos alter their mass to change their flavour (ie. an electron neutrinos gain mass to change to a muon neutrino). This would also explain the relative lack of electron neutrinos, thus solving the solar neutrino problem!


What is anti-neutrino?

An antineutrino is the antimatter counterpart to a neutrino. It has no electric charge, very low mass, and interacts very weakly with matter. Antineutrinos are produced in nuclear reactions, such as in the Sun or nuclear reactors.


What is the smallest unit made up of?

Units of measurement aren't made up of anything. The smallest unit of measurement is the Plank unit - 10^-35m. The smallest sub atomic particle is a Neutrino, and it is made up of, a Neutrino!


Are atoms the smallest particles of matter?

No. The smallest particle of matter appears to be the electron neutrino, with a mass somewhat less than 2.2 eV. Even the electron, at 511 eV, is massive, compared to the neutrino.


What is the amu of a neutrino?

Three different types of neutrinos are recognized. The latest work on the subject suggests that the combined mass of one of each type adds up to less than one billionth of an AMU.


A Neutrino travels at the speed of light which is a constant. How can it have different energies.?

The speed of a neutrino is close to the speed of light. Neutrino's have different energies based on mass. There are three neutrinos each of varying mass and therefore of different energies. So, a Tao flavored neutrino has more mass than an electron flavored one giving it more energy, however due to relativity it will travel slower based on it's mass. This can happen because they have mass. In the case of a photon (i.e. a massless particle) the energy is based on electromagnetic frequencies, however this determines the way in which light gets scattered when it hits different mediums. Though most of this stuff is covered in most modern physics books and classes.
