Answer:

Radiation

Step-by-step explanation:

Heat is a form of energy that flows due to temperature difference. It can be transferred either by conduction, convection or radiation.

Conduction mainly take place in solids, convection in fluids (liquids and gases), while radiation takes place in gases.

Radiation is a process of heat transfer from the source to a detector without heating the intervening medium. It do not require material medium for its propagation.

Thus, the process by which heat traveled from the candle towards the daughter's hand is called radiation.
