Harper, Abigail, and Ethan are studying nuclear physics. They come across a term 'gamma decay'. Harper explains it as a real-world scenario. How does Harper describe gamma decay?

• Harper says, 'Imagine an unstable atomic nucleus in a radioactive material. Gamma decay is like this nucleus emitting a high-energy photon.'

• Harper says, 'Imagine an unstable atomic nucleus in a radioactive material. Gamma decay is like this nucleus releasing an electron.'

• Harper says, 'Imagine an unstable atomic nucleus in a radioactive material. Gamma decay is like this nucleus emitting a low-energy photon.'

• Harper says, 'Imagine an unstable atomic nucleus in a radioactive material. Gamma decay is like this nucleus absorbing a high-energy photon.'

Ava, Mason, and Henry are studying nuclear physics. They come across a nuclear reaction where no physical particle is emitted, but the energy is released. They are confused about which particle is emitted in this scenario. Can you help them identify the particle emitted during this gamma decay?

Zoe, Grace, and Anika are studying nuclear physics. They came across a term 'half-life'. What does 'half-life' mean in their context?

• The time it takes for half of the atoms in a radioactive substance they are studying to double.

• The time it takes for half of the atoms in a non-radioactive substance they are studying to decay.

• The time it takes for half of the atoms in a radioactive substance they are studying to decay.

• The time it takes for all of the atoms in a radioactive substance they are studying to decay.
