Visible Light Spectrum
Does the sun give off invisible light rays called microwaves?
Asked in The Moon, Visible Light Spectrum
Does light from the sun give off more visible light or more invisible light?
The Sun gives off more invisible light because the Sun gives off all the light in the Electromagnetic Spectrum. Radiowaves, Microwaves, UV rays, Visible light, X-Rays and Gamma Rays. I might have missed some but I think I got all of them. The only kind of light we can see is Visible light. Therefore, the Sun gives off more invisible light then visible light.

Asked in Microwave Ovens
Are microwave ovens the same as microwaves?
A microwave is a form of electromagnetic radiation in the frequency range between 300 MHz (or 0.3 GHz) and 300 GHz. A microwave is also the "shorthand" name we give to a common appliance called a microwave oven. Are they the same? Whether or not microwave ovens are the same as microwaves depends on the application of the term. Microwave ovens are called that because they contain a microwave generating device and direct the radiated electromagnetic energy (the microwaves themselves) into a cooking space (called a cavity) to heat drinks or food, or even to cook things. Say an appliance salesman is saying to his/her junior helpers, "Arrange the microwaves on the shelves." This refers to the microwave ovens. It's not about electromagnetic energy called microwaves. Take the case of an electronics teacher saying to his/her students, "The microwaves are reflected off the metal screen that is used in the construction of the dish." This does not refer to microwave ovens, but the electromagnetic energy itself.
Give you ideas about investigatory project in physics?
Investigatory projects in physics Measure speed of light with Microwave oven Microwaves and light both are electromagnetic waves. We can measure speed of light by measuring speed of microwaves. Place a marshmallow in microwave oven and heat it until it begins to melt in three or four spots. Measure the average distance between these spots.This is the half wavelength of microwaves. Find the label on the back of the oven to find the frequency of microwaves. Multiply it by wavelength, it is the speed of light. Effect of solutes on boiling temperature of solvent Heat up a pure solvent and measure its boiling temperature by thermometer.Now add measured amount of solute to boiling solvent. Measure the temperature again. Repeat the experiment with different amounts of solute. Compare the boiling temperature of pure solvent and boiling temperature of its solution with a solute.
