How does a light bulb's wattage affect the heat detected above a light?
the higher the wattage is the hotter it gets
Which type of electromagnetic wave will be emitted by a hotter object?
Hot objects emit electromagnetic waves at frequencies in a wide range starting from the infra-red, which is invisible to humans but is easily detected by other animals and man-made heat-detector instruments, up to higher, visible light.
What electromagnetic wave IS perceivable by humans?
The "visible light" spectrum, known as "visible light", is perceived by receptors at the back of our eyes, and a portion of the infrared spectrum, known as "heat" is detected by nerve endings in our skin.
Why is heat energy harder to see then light energy?
Our eyes do not respond to heat waves, which is why we cannot see them. Light waves, on the other hand, are detected by our eyes and this makes us see.
Why cant humans detect infrared light?
They can. While human eyes can not "see" infrared light, humans can detect this light as "heat" on the surface of the skin.
How do animals lose heat after exercise?
Instead of sweating like humans, the pant.
How do mountain animals deal with the weather?

How different would earth be without he atmosphere?
No life would be able to sustain the harsh heat, violent rays, and blinding light by the sun, not to mention humans and animals wouldn't be able to breath...
How important is the sun to the earth and why?
the sun is really important for life. because sun is necessary for plants so the sun is necessary for plant eating animals. and meat eating animals eat plant eating animals so the sun is necessary for meat eating animals. also humans eat meat eating animals and plant eating animals so it is necessary for humans. it also generates light and heat. hope u are not confused :D
Is all of the electricity used to light a light bulb useful light?
No. Part of the energy is wasted, mainly as heat.
What can differences in heat be detected by?
Infared cameras.
