What else can I help you with?
How do microwave ovens allow light to escape but not microwaves?
Both visible light and microwave radiation are different variations of the same electromagnetic energy. Visible light has infinitesimally small wavelengths, and therefore it can pass through the screen holes. Microwave radiation has much larger wavelengths, and these wavelengths are too big to "fit" through the screen holes, and therefore the screen appears solid to the microwave radiation. The microwave radiation is therefore completely reflected by the screen.
Which has higher frequencies microwaves or visible lights?
Visible light has shorter wavelengths than microwaves. Microwaves, which might be considered the highest energy radio waves, have a longer wavelength (and a lower frequency) than visible light.
Which has higher frequency microwaves or tv waves?
In the entire spectrum of electromagnetic waves, microwaves and radiowaves (microwaves are sometimes classified under radio waves), have the longest wavelengths, and the lowest frequencies (and therefore, energy).
What happens in a microwave?
A microwave is simply an instrument for producing microwaves ( these are similar to that of infra-red and radio waves), these microwaves that are produced in the microwave itself has the same wavelength of water and allows water molecules to vibrate. The increase in energy of these water molecules (the kinetic energy) can then be transfered (as energy is never created or destroyed) into heat energy. Therefore heating up the food/drink or what ever you are placing in the microwave, this is essentially how it works.
What type of electromagnetic radiation has longer wavelengths than human eye can detect?
Infrared radiation has longer wavelengths than the human eye can detect. These wavelengths are longer than those of visible light, allowing infrared radiation to be used for thermal imaging and night vision technology.

Do gamma rays have more energy than microwaves?
Yes, gamma rays have much more energy than microwaves. Gamma rays are a form of electromagnetic radiation with the highest energy and shortest wavelength in the electromagnetic spectrum, while microwaves have much lower energy and longer wavelengths.
What is the energy conversion for a microwave?
Microwave radition is part of the electromagnetic spectrum. They are located higher than that of the visible spectrum (light) because they are shorter in wavelength (higher in energy) Sorry, but your answer is incorrect. Microwaves are much lower in frequency and have longer wavelengths than visible light: Frequency Wavelength Quantum Energy (eV) Microwaves 300 MHz - 300 GHz 1 meter - 1 millimeter 0.00001 - 0.001 Light ~5,000,000 GHz ~ 0.0006 millimeters 1.65 - 3.1 Therefore, there is a lot more energy in visible light: longer wavelength = lower energy
The slower an object vibrates the longer wavelength will be?
Yes, the wavelength of a wave is inversely proportional to its frequency. As frequency decreases, the wavelength increases. Therefore, if an object is vibrating more slowly, it will produce waves with longer wavelengths.
Do waves with longer wavelengths have higher or lower frequency's?
Waves with longer wavelengths have lower frequencies. The frequency of a wave is inversely proportional to its wavelength, so as the wavelength increases, the frequency decreases. This relationship is represented by the equation: frequency = speed of wave / wavelength.
Which wavelength has more energy short or long?
Short wavelengths has more energy. (X-rays Gamma rays belongs to this category.) Long wavelengths has less energy (radio waves and light belongs to this category). I hope this would be enough.
Is microwave harmful to human body?
The Wavelenght of microwaves is between 1m to 1mm, the visible light has a wavelength of ca 350nm-750nm. A Short wavelenght means a high frequency and fequency indicates a high energylevel. Therefore Micorwaves have a verylow energy, comparet with the normal light. So: It is harmless! Neramo
How are pitch and wavelength the same?
Pitch and wavelength are related in that pitch corresponds to the frequency of a sound wave, while wavelength corresponds to the physical distance of one complete cycle of the wave. As pitch increases, the frequency and therefore the rate of oscillation of the wave increases, leading to shorter wavelengths. Similarly, as pitch decreases, the frequency decreases and the wavelengths become longer.
