Will two sounds of 50 db constitute a sound of 100 db . Explain

1 answer:

6 0

Two sounds of 50 db each will NOT constitute a 100 db sound. This is because, the relation that relates levels of sounds is a logarithmic relation and not a direct relation of addition. <span>Each 10 dB increase in sound makes the sound 10 times louder.
</span>This means that, for 50 db, the resultant sound level will be <span>twice as loud is an increase of 10Log (2) = 3.01dB
</span>
The final sound level = 50 + 3.01 = 53.01 db

Use the passage to answer the question.

Zielflug [23.3K]

The reasoning in the passage is : ( C ) The spots are the result of interference, which happens with waves but not particles

<h3>Light waves </h3>

Light passed through a slit and projected onto a screen will form a pattern which is very visible and the pattern might have dark spots if there is some form of interference. Interference is present in waves and not particles.

Hence we can conclude that the reasoning in the passage is The spots are the result of interference, which happens with waves but not particles
