What is decreased signal intensity?
A fudge i give
What unlessened mean?
It means not decreased; continuing at the same rate or intensity.
What will happen if cover half of the concave mirror?
Intensity of image decreased
Does the intensity of a wave increases when its amplitude decrease?
Intensity of a wave is proportional to the square of its amlitude so it should decrese when the amplitude is decreased.
What is the definition of decreased?
to grow progressivly less in size,amount,number,or intensity
What is meant by the terms acoustic impedance and attenuation?
Acoustic impedance is the measurement that indicates how much sound pressure the vibration of molecules at a given frequency is generated. Attenuation refers to the gradual loss in intensity through a medium, such as light and sound in water.
What is hypochromicshift?
Hypochromic shift is observed in UV VISIBLE spectroscopy. This is the shift where the intensity of the absorption maxima is decreased
Which attenuate the sound pressure level?
Noise and Attenuation. Noise is usually defined as unwanted sound - noise, noise generation, silencers and attenuation in HVAC systems. Attenuation of Sound Waves: When sound travels through a medium, its intensity diminishes with distance. In idealized materials, sound pressure or signal amplitude is only reduced by the spreading of the wave. Natural materials, however, all produce an effect which further weakens the sound. This further weakening results from scattering and absorption. Scattering is the reflection of the sound in directions other than its original direction of propagation. Absorption is the conversion of the sound energy to other forms of energy. The combined effect of scattering and absorption is called attenuation. Ultrasonic attenuation is the decay rate of the wave as it propagates through material. A property of some thing or action which is essential and specific to that thing or action. Attenuation of sound within a material itself is often not of intrinsic interest. However, natural properties and loading conditions can be related to attenuation. Attenuation often serves as a measurement tool that leads to the formation of theories to explain physical or chemical phenomenon that decreases the ultrasonic intensity.
When you turn down the volume what happens to the sound waves' amplitude?
Intensity of sound is dealt as volume in case of radio sets. Intensity is directly proportional to the square of amplitude. So as volume is turned down, intensity is reduced and so the amplitude is decreased.
When you turn down the volume what will happen to the sound waves' amplitude?
Intensity of sound is dealt as volume in case of radio sets. Intensity is directly proportional to the square of amplitude. So as volume is turned down, intensity is reduced and so the amplitude is decreased.
How do non-lead aprons shield from radiation?
The attenuation factor is the main focus in radiation protection. Attenuation is the gradual loss of intensity of a current as it passes through a medium. Lead was found to be effective at attenuating radiation so it became the industry standard. Through research and development, other metals (tin, bismuth, aluminum, barium, and titanium) have been found to attenuate x-rays efficiently while still meeting the lead equivalency.
What is the relation between amplitude and loudness?
Sound is a mechanical wave. This means it needs a material medium to travel through. The loudness ie the intensity of sound is directly proportional to the square of the amplitude. As the sound wave passes through, due to elasticity of the medium the energy will be lost and so the amplitude gets decreased. So at far distance the sound intensity will be very feeble.
