Describe how light and sound waves are affected when they move from air to water.
Answer:
When the light wave moves from air to water, it slows down. This change in speed causes the light wave to bend. Refraction is the change in direction of a wave when it changes speed as it travels from one material to another.
Explanation:
The light wave slows down when it transitions from air to water. The light wave bends as a result of this velocity change. When a wave changes speed while moving from one substance to another, it changes direction, which is known as refraction.
What is refraction?Refraction is defined as a wave's shift in speed causes it to alter direction as it travels from one medium to another. Since the densities of glass and air are different, a line or spot of ink on a piece of paper will always appear to be raised when viewed through the glass slab. Due to light refraction, a coin or stone that is at the bottom of a container filled with water appears to be lifted.
A sound wave's characteristics will alter when it passes from air to water. Because crests move away from the boundary quicker than they move up to the boundary, the wave speed will increase when the wave crosses the boundary into the sea, increasing the distance between crests (the wavelength).
Thus, the light wave slows down when it transitions from air to water. The light wave bends as a result of this velocity change. When a wave changes speed while moving from one substance to another, it changes direction, which is known as refraction.

Please i need help asap i will do 30 points it is a weather question the only thing i know is that you have to add them all up and put them to percentages like 20/80 = 25%
Answer:
Drought is 19%
Flooding is 9%
Freeze is 2%
Severe storm is 15%
Tropical cyclone is 48%
Wildfire is 3%
Winter storm is 4%
Explanation:
220 + 108 + 25 + 178 + 550 +31 + 41 = 1153
Basically, you take the number of each natural disaster plus it all together. That is your total.
You then take individually the number and divide it by the total (1153), once you get a decimal number you times it by 100. Which give you the percent
You then do this for the rest of the other natural disasters.

Answe
for 12, the possiblility of the child having widows peak is 100% and the possibility of it having no widow peak 0%. For 13, The probability of the child having a widow's peak is 75%. The possibility of the child not having one is 25%. Hope this helps.
Answer: 100%, 0%, 75%, 25%
Explanation:
For 1 and 2, All of the genotypes have 1 capital which makes it widows peak 100 %, hairline 0 %. For 3 and 4, one of the genotypes have both lowercase (tt), which makes it 25 % chance of getting a straight hairline.

Which of the following would cause the most soil to erode away?
A.
having very little rainfall for a year
B.
planting new trees in a flat area.
C.
pulling out plants and leaving the ground bare
D.
putting heavy rocks over the ground
HELP ME IF YOU DARE.
When the earth is exposed to high winds, heavy rains, and moving water, soil erosion predominantly takes place. Some human activities, like farming and clearing land, make the soil more prone to erosion, hence option D is correct.
What is soil erosion?Due to its abundance and strength, running water is the main contributor to soil erosion. Because wind can take up soil and carry it great distances, the wind is another major contributor to soil erosion.
Activities that enhance erosion include those that clear vegetation, disrupt the soil, or let it dry out.
Therefore, the soils that contain the most particles of a medium (silt) size are the ones that are most prone to erosion, hence option D is correct.
