How do you make a sound wave’s pitch lower?

1 answer:

7 0

Sound travels more slowly than light. Sound waves travel at the same speed, but vibrate in different ways. when sounds vibrate slowly they give a lower pitch

A school bus moves slower and slower. Using what you have learned about forces, explain why the bus moves slower and slower.

Levart [38]

Answer:

I don't exactly know what you learned but it could be because of more friction or the bus was running out of gas.

Light in vacuum is incident on the surface of a slab of transparent material. In the vacuum the beam makes an angle of 39.9° wit

wariber [46]

Answer:

n=2.053

Explanation:

We will use Snell's Law defined as:

$n_{1}*Sin\theta_{1}=n_{2}*Sin\theta_{2}$

Where n values are indexes of refraction and $\theta$ values are the angles in each medium. For vacuum, the index of refraction in n=1. With this we have enough information to state:

$1*Sin(39.9)=n_{2}*Sin(18.2)$

Solving for $n_{2}$ yields:

$n_{2}=\frac{Sin(39.9)}{Sin(18.2)}=2.053$

Remember to use degrees for trigonometric functions instead of radians!
