Leaving one light bulb on unnecessarily can waste a significant amount of energy over time. The exact amount depends on the type of bulb (incandescent, LED, etc.) and its wattage. However, generally speaking, it is more energy-efficient to turn off lights when they are not needed to help reduce energy waste.
Light, of course, since that's what the light bulb is designed to produce. There is also waste energy, as heat, and (to a small extent) as sound.
Depends on your definition of waste. The obvious one is heat unless you are using bulb for an Easy Bake oven in which case the light might be considered waste and heat the primary usage. One could also say that in certain bulbs perhaps there are some light frequencies that may be annoying or not useful.
To plug it in, you use your muscle energy. When current flows through the bulb,electrical energy converted to the heat and light energy in the bulb.
The energy that goes in is electrical energy; the energy that leaves it is visible light, as well as heat.
A light bulb uses electrical energy, and produces light, as well as heat.
A lot
Mainly heat.
Electricity is the type of energy that is used when you turn on a light bulb. When you leave a room, you use more energy by leaving the light on than if you turn it off and back on when you return.

The light bulb uses electrical energy, and produces light, as well as waste heat. The act of turning it on in itself uses a small amount of energy stored in your muscles.

A light bulb converts electrical energy into light energy and heat energy.
No.it uses energy sources (electrical energy to light up
In a light bulb, electrical energy is transformed into light energy and heat energy.
