Explain why a light wave refracts when it travels through mediums such as air to water.

Answers

Answer 1
Answer: The simplest explanation is that the speed changes. That causes the wavefront to change direction and so refraction takes place.

Which of the following is a true statement? A) It's easier to lift a heavy weight straight up than to slide it up a ramp. B) When you use a lot of effort, a load becomes lighter. C) When you use a minimum amount of effort, a load becomes heavier. D) When you increase the distance over which effort is expended, you don't have to work as hard.

Answers

Answer:

D) When you increase the distance over which effort is expended, you don't have to work as hard.

Explanation:

This statement reflects one of the principles of mechanical advantage. When you increase the distance over which effort is applied (in situations like using a lever or a simple machine), it allows you to achieve the same work with less force. It's the concept of trading off force for distance, which is a fundamental principle in physics and mechanics.

An article in a magazine denies that Earth is warming and climate change is occurring. The writer reports that this season was the snowiest winter on record for the Northeast, with lower than average temperatures for the region. Because of the low temperatures, the writer concludes that climate change cannot possibly be occurring. What question should you ask the writer to clarify whether his stance on climate change is scientifically sound?(A) Did the snowstorms cause extensive damage?
(B) Was this the coldest month on record for this region?
(C) Were the snowfall totals of each storm larger or smaller than last year?
(D) Were long-term temperature changes investigated in addition to short-term change?

Answers

D.
This is likely to challenge the writer's stance because one piece of data cannot accurately depict a long-term trend.`
