AI Thread Summary
In the discussion on Snell's Law, a wave transitions from deep to shallow water with given angles of incidence and refraction. The key equation to analyze the ratios of frequency, velocity, and wavelength is sinθ1/sinθ2 = v1/v2. Participants clarify that a ratio represents a division, exemplifying it with numerical ratios like 1:2. To fully understand the relationships, it's important to extend the equation to incorporate wavelength as well. This understanding is crucial for solving the homework problem effectively.

Homework Statement



A wave in a ripple tank moved from deep to shallow water with angle of incidence of 70' and angle of refraction of 55'. What are ratios in two media of the frequencies, velocities, wavelengths.

What does it mean by the ratio?

Homework Equations



sinθ1/sinθ2=v1/v2.

The Attempt at a Solution



I have no clue how to do this or understand the question. Would they be the formula sinθ1/sinθ2=v1/v2.

Need some urgent help thanks!

A ratio is like division, the ratio of a to be is written as a:b or a/b.

so if your ratio of a:b is 1:2 you can write a/b = 1/2 = 0.5.

For you relevant equation, you will also need to extend that to include wavelength.

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
