Finding Wavelength and Velocity of an Ocean Wave.

AI Thread Summary
To find the wavelength and velocity of an ocean wave, the key equation is wavelength (λ) times frequency (f) equals velocity (v). Given the water depth of 300m, frequency of 8 seconds, and amplitude of 3m, the wavelength can be derived using the formula λ = v/f. However, the velocity cannot be calculated directly due to the lack of a specific variable, necessitating numerical methods for a solution. Measuring the wavelength involves determining the distance from crest to crest, but this information is not provided in the initial data. The discussion emphasizes the need for numerical methods to solve for velocity when certain variables are missing.

v=velocity

The Attempt at a Solution



I have 2 missing variables for both of the above equations.
Am I missing a variable or equation?

Thanks.

To find the wavelength of an ocean wave you just need to measure from crest to crest.

if only that were in the given data
 
If you replace \lambda in your equation according to
\lambda = \frac{v}{f} where f is known
you will have an equation with only one unknown, v.
However this equation cannot be solved analytically but only by numerical methods.
 
Thread 'Voltmeter readings for this circuit with switches'
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...
