Can atoms change energy levels?
no, electrons can
What is db levels?
The decibel (db) is a logarithmic unit that indicates the ratio of a physical quantity (usually power or intensity) relative to a specified or implied reference level
How many times louder is a sound wave with an intensity of 50dB than a sound wave with an intensity of 20dB?
Better think of the sound pressure, when you are listening. Sound pressure moves your ears and the diaphragm of the microphones. The sound intensity is very small. The level of 50 dB is equal to 0.0000001 W/m2 acoustic intensity. Scroll down to related links and look at "Conversion of sound units (levels)".
What is the purpose of mentioning db in audio system and how db works?
The dB mentioned when speaking of audio is referring to the decibel. The decibel is used to measure sound level. The purpose of mentioning it is for those who look for certain dB levels. The dB is a common measure of sound intensity that is 1 tenth of a bel on the logarithmic intensity scale.
Latent heat energy levels?
The latent heat energy levels refers to the heat absorbed during a change phase at a constant pressure and temperature.
As light intensity increases the rate of photosynthesis?
Initially increases then levels off. (the rate of photosynthesis) Hope that helped!!
As light intensity increases the rate of photsynthesis?
As light intensity increases at first the rate of photosynthesis also increases. However at higher light intensities the rate of photosynthesis levels off and becmes constant. This is because light is not the only factor needed for photosynthesis. So at high light intensities some other factor is running out eg CO2, temperature, so the extra light cannot be used. At very high intensities photosynthesis can decrease as the chlorophyll is bleached.
Why does the rate of photosynthesis increase as light intensity increases?
I believe that it increases. -_-
How does light intensity affect the rate of photosynthesis?
Higher light intensity increases the rate of photosynthesis and vice versa.more intense light means more energy in the light, so the chloroplasts get more energy from light, making photosynthesis go faster
If you continue to increase the intensity of light that a plant receives what happens?
As the light intensity increases, the rate of photosynthesis will increase and then level off no matter how much brighter the light gets. This is because another limiting factor such as carbon dioxide or water level stops it. If the light gets too bright the heat can burn the leaves.
What is the relationship between an increase in light intensity and photosynthetic rate in tomato leaves?
As light intensity increases then the rate of photosynthesis increases until a point is reached when the rate levels off. Beyond this point is called the light saturation point of photosynthesis.
Sound pressure levels comparison?
Comparison of Sound Pressure and Sound Intensity Levels. Scroll down to related links and look at "Comparison of Sound Pressure and Sound Intensity Levels".
How is high cholesterol levels a risk factor for ischemia?
Risk of developing coronary artery disease increases as blood cholesterol levels increase. When combined with other factors, the risk is even greater.
Can you give me a sentence with the word intensity?
The energy intensity levels on the machine are 100% higher than expected
What factor reduces the accuracy radiocarbon dating?
Atmospheric carbon-14 levels change over time
What is the phase of the mesocycle is characterized by high levels of intensity?
endurance
As sound intensity increases you hear the sound as a louder sound at the same pitch this suggest what?
There we got: Subjectivly sensed loudness (volume), objectively measured sound pressure (voltage), and theoretically calculated sound intensity (acoustic power). Scroll down to related links and study: "Dependance of sound levels and the corresponding factors".
