In young's double slit experiment the intensity of central maximum is Io what will be the intensity at the same site if one of the slits is closed?
It should be I0/2
How does the intensity of a 40-decibel sound compare to the intensity of a 20-decibel sound?
Given: Sound intensity level LI1 = 40 dB and sound intensity level LI2 = 20 dB. Reference sound intensity Io = 10^−12 W/m² (Threshold of hearing) Reference sound intensity level LIo = 0 dB-SIL (Threshold of hearing level) Get sound intensity I1 when entering sound intensity level LI1 = 40 dB: Sound intensity I1 = Io×10^(LI/10) W/m² = 10^−12×10^(40/10) = 0.00000001 W/m² = 10^−8 W/m². Get sound intensity I2 when entering sound intensity level LI2 = 20 dB: Sound intensity I2 = Io×10^(LI/10) W/m² = 10^−12×10^(20/10) = 0.0000000001 W/m² = 10^−10 W/m². The sound intensity I1 = 10^−8 W/m² is 100 times more than the sound intensity I2 = 10^−10 W/m². The sound intensity level LI1 = 40 dB is 20 dB more than the sound intensity level LI2 = 20 dB.
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 decibel formula?
The decibel, or dB, is a means of expressing the gain of an active device (such as an amplifier) or the loss in a passive device (such as an attenuator or length of cable). It is simply the ratio (!) of output to input expressed in logarithmic form. The decibel was developed by the telephone company to express the gain or loss in telephone transmission systems.Sound intensity (sound energy quantity):Reference sound intensity Io = 10^−12 W/m² (Threshold of hearing)Reference sound intensity level LIo = 0 dB-SIL (Threshold of hearing level)Get sound intensity I when entering sound intensity level LI:Sound intensity I = Io×10^(LI/10) W/m² = 10^−12×10^(LI/10) W/m².Get sound intensity level LI in dB when entering sound intensity I in W/m²:Sound intensity level LI = 10×log (I / Io) dB = 10×log (I / 10^−12) dB.Sound pressure (sound field quantity):Reference sound pressure po = 20 µPa = 2×10^−5 Pa (Threshold of hearing)Reference sound pressure level Lpo = 0 dB-SPL (Threshold of hearing level)Get sound pressure p when entering sound pressure level Lp:Sound pressure p = po×10^(Lp/20) Pa or N/m² = 2×10^−5×10^(Lp/20) Pa.Get sound pressure level Lp in dB when entering sound pressure p in Pa:Sound pressure level Lp = 20×log (p / po) dB = 20×log (p / 2×10^−5) dB.
Does io have gravity?
Io's gravity is 1.796 m/s2 (0.183 g) If you weighed 100 kg on Earth, you'd weigh 18.3 kg on Io.
What causes instruments which uses the beer's law to read negative values?
Incorrect measurement of the incident intensity, Io. If the measurement if Io is less than the transmitted intensity, I, then the absorbance read-out (calculated as log(Io/I) will be negative. This error usually results from unmatched or misaligned cells, or in an improper blank solution (used to measure the Io signal). Tom O'Haver http://terpconnect.umd.edu/~toh/

What is the intensity of a sound at the pain level of 120dB?
If you think the threshold of pain is the sound intensity level of LI = 120 dB than you can convert that value to sound intensity I. Reference sound intensity Io = 10^−12 W/m² (Threshold of hearing). Reference sound intensity level LIo = 0 dB-SIL (Threshold of hearing level). Get sound intensity I when entering sound intensity level LI = 120 dB. Sound intensity I = Io×10^(LI/10) W/m² = 10^−12×10^(120/10) W/m² = 1 W/m².
How to measure optical depth of atmospheric aerosols due to molecular scattering?
send a beam of light through the air, measure the intensity before (Io) and after (I) it goes through. optical depth = -ln(I/Io).
What does 70 dB sound like?
Given: Sound intensity level LI = 150 dB. Reference sound intensity Io = 10^−12 W/m² (Threshold of hearing) Reference sound intensity level LIo = 0 dB-SIL (Threshold of hearing level) Get sound intensity I when entering sound intensity level LI = 150 dB: I = Io×10^(LI/10) in W/m² = 10^−12×10^(150/10) = 1000 W/m².

What is sound intensity measured in?
Reference sound intensity Io = 10^−12 W/m² (Threshold of human hearing). Reference sound intensity level LIo = 0 dB-SIL (Threshold of human hearing intensity level). The sound intensity I is measured in watts per meter squared. The sound intensity LI level is measured in decibels (dB).
What is IO mapped?
Peripheral-Mapped IO is IO that is selected when the IO/M- line is high.
What does io mean in English?
If you are referring to the Italian word 'Io' which can be used in the sentence 'Io Sono', Io means I. Io sono means I am.
What is Peripheral-Mapped IO?
Peripheral-Mapped IO is IO that is selected when the IO/M- line is high.

Differentiate between memory mapped IO and IO mapped IO?
Memory mapped IO is one where the processor and the IO device share the same memory location(memory) while IO mapped IO is one where the processor and the IO device have different memory located to each other.
