How are sound waves different from other waves?

Physics
1 answer:
olganol [36]2 years ago
5 0
Hello there! Sound waves differ from other waves (electromagnetic waves in particular). Sound waves differ from these because:

• They require a medium (solid, liquid, or gas)

• They cannot travel through the vacuums of space

• They require matter to travel

• They emit a different natural sense from electromagnetic waves, which is sound

If you need any help, let me know and I will gladly assist you.

Fehling's solution is added to the counters of test tube b after about 3 minutes and it turns brick red.what food substance was
hjlf

The food substance being used which turned Fehling's solution to brick red is a reducing sugar.

<h3>What is Fehling's solution?</h3>

This is an indicator which is used to test for the presence of reducing sugar or aldehydes in a solution.

Brick red precipitate of copper(I) oxide is formed when it tests positive to compounds such as glucose etc.

I NEED HELP PLEASE, THANKS! :) Why does the pattern of colors repeat in a thin soap film?
Nadusha1986 [10]

Answer:

When white light shines on the bubble, it acts as a prism. While some of the white light bounces back off, some of them pass through the prism forming fringes of colors. But then, they too bounce off the inner part of the film. So one set of light rays shine into a soap bubble, but two sets of rays come back out again. When they emerge, the waves that bounce off the inner film have traveled a tiny bit further than the waves that bounced off the outer film. So, we have two sets of light waves. After that, the waves starts merging (Just like the ripples in the pond) . Some add together while some cancel out. That is why we see the pattern of colors repeating in the thin film soap.

A crane lifts a 1,750 kg mass using a steel cable whose mass per unit length is 0.88 kg/m. What is the speed of transverse waves
Sauron [17]

Answer:

139.6m/s

Explanation:

Calculate the tension first, T=m*g

mass(m): 1750kg, gravity(g): 9.8m/s^2

T= 1750*9.8

 =17150N

Then calculate the wave speed using the equation v = √ (T/μ)

v= √(17150N)/(0.88kg/m)

 =139.6m/s
