Mr. and mrs. tew attended this summer band concert to her their son play his violin. when they sat down in their seats, they noticed that there were dead moments. that is, places in the music when they could not hear anything! they decided to move and sit directly in front of the band in the third row. how can you explain the dead spots they experienced?

The dead spot experienced was due to the effect of sound wave interference

Explanation:

Sound wave interference occurs when wave interact. They can interact constructive manner increasing each other's strength and rising the intensity of the final wave produced.The waves can also interact destructively reducing each other's strength and intensity.In some cases, destructive interaction causes a total cancelling of the waves resulting to places where no sound can be heard at all.This area is the dead spot.

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
