What is an example of radient energy?
Radiant energy is basically light energy Ex. Light bulb lantern The sun
What are some uses of light energy?
some uses of light energy are Light energy is used in photosynthesis for plants because plants need light to grow. Light Energy can be used in producing electricity and it also be used for generating heat.
What happens to light energy when it strikes what happens to light energy when it strikes a leaf?
When light energy strikes a leaf, some of it is absorbed by pigments in the leaf for photosynthesis, some is reflected, and some is transmitted through the leaf. The absorbed light energy is converted into chemical energy by the leaf for use in metabolic processes.
What is an object that reflects some light and transmits some light?
Reflects light : Non-luminous (Ex. Moon) Transmits Light : Luminous (Ex. Sun) I hope you got it! -Ajlan Wasfi Khan
What is the energy transformation of a flatshlight?
A flashlight transforms electrical energy into light energy and some heat energy. When the battery powers the flashlight, the electrical energy is converted into light energy when the bulb or LED emits light, while some of the energy is also lost as heat.
What energy changes are involved when an electric light shines?
When an electric light shines, electrical energy is converted into light energy and heat energy. The electrical energy is converted into light energy, which is the main purpose of the light bulb, while some of the energy is also released as heat energy due to the resistance in the light bulb filament.
Does light bulbs convert into chemical energy?
No. The energy that goes into a light bulb is electrical energy, the energy that comes out is electromagnetic radiation, which we perceive as mostly heat and some light.
When a lightbulb is lit electrical energy is changed into light energy and?
Some of the electrical energy is converted into light energy, while the rest is converted into heat energy. The light energy produced is a result of the light bulb’s filament getting hot enough to emit visible light.
Which colors are best for saving energy in hot or cold clilmates?
Dark colours (ex: black) absorb and keep heat. Light colours (ex: white) reflect heat.
What energy is wasted in light bulbs?
Some of the electrical energy is given off as heat not visible light.
What type of energy transformation occurs when a light bulb is turned on?
Electricity is transformed into light and heat energy when a light bulb is turned on. The electrical energy is used to heat up the filament in the bulb, causing it to glow and emit light. Some of the electrical energy is also converted to heat energy due to resistance in the filament.
Describe the way energy changes form when an electric light is turned on?
When an electric light is turned on, electrical energy is converted into light energy and heat energy. The electrical energy powers the light bulb, causing it to emit light. Some of the electrical energy is also transformed into heat energy due to the resistance within the light bulb.
