Yes. Heat is radiated as infra-red, a longer wavelength than visible light, but otherwise similar. Incandescent light bulbs with a heated filament emit infra-red light as heat, and only a small part of the emission is visible. Other light bulbs using electrical discharges in neon gas (known as fluorescent bulbs) do not produce as much infra-red, and are more efficient in the conversion of electrical energy into light. If you feel a fluorescent tube you will find it is only warm, but DO NOT feel an incandescent bulb or you will burn your hand, its so hot.

Does the spring in a flashlight complete the circuit or does it convert electrical energy into light energy?
The spring in a flashlight completes the circuit by providing a connection between the battery and the light bulb. It does not convert electrical energy into light energy - the light bulb does that function.
What are similar to motors except they convert mechanical energy to electrical energy?
Generators are similar to motors in that they both involve the conversion of energy, but generators convert mechanical energy into electrical energy, whereas motors convert electrical energy into mechanical energy.
How are both motors and generators examples of energy changing form?
Motors convert electrical energy into mechanical energy to produce motion, while generators convert mechanical energy into electrical energy. In both cases, energy is changing from one form to another - from electrical to mechanical or vice versa.
When a light bulb is lit electrical energy is changed into light energy and?
heat energy. The electrical energy powers the light emission in the bulb, producing both light and heat as byproducts of the process.
What types of energy are in a light globe?
A light globe typically converts electrical energy into light and heat energy. The electrical energy powers the light bulb which produces both light (radiant energy) and heat (thermal energy) when it is illuminated.

When a lamp is turned on electrical energy changes into what form of energy?
The older generation of bulb(one in witch heating metal coil was used) convert electrical energy into both heat and light energy and consume more energy as some energy is lost as a heat energy. The newer generation of electrical bulb (C.F.L.) convert almost all electrical energy into light energy and consume much less electrical energy.

A 100 watt light bulb converts electrical energy into electromagnetic energy at a slower rate that a 40 watt light bulb?
This statement is incorrect. The rate at which electrical energy is converted into electromagnetic energy is determined by the wattage of the light bulb. A 100-watt light bulb will convert electrical energy into electromagnetic energy at a faster rate than a 40-watt light bulb.
How are speakers and motors alike?
Speakers and motors both convert energy into mechanical motion. They both have coils of wire that interact with a magnetic field to produce movement. However, the main difference is that speakers convert electrical energy into sound waves, while motors convert electrical energy into rotational motion.
What are the energy transfers that occur in a flashlight?
In a flashlight, electrical energy from the battery is converted into light energy and heat energy in the bulb. The battery provides the electrical energy, which powers the light bulb to produce both light and heat.
Into what two forms of energy is electrical energy changed into a light bulb?
batterys
What do toasters and light bulbs have in common?
Toasters and light bulbs are both electrical appliances that convert electrical energy into heat or light. They both use a filament or coil that heats up when electricity passes through it, though the purpose and outcome of the heat produced is different for each appliance.
Is it true that A light bulb converts electrical energy into both heat and light energy.?
Yes, it's true. When a light bulb is turned on, most of the electrical energy is converted into heat, but some of it is also converted into light energy. This is what allows the light bulb to produce light.
