If wavelength changes does speed change

AI Thread Summary
In the context of standing waves, if the wavelength changes, the speed of the wave will also change, as defined by the equation velocity = wavelength * frequency. A standing wave is characterized by being in a constant position, meaning it does not propagate through space like traveling waves. While there is some uncertainty, it is suggested that standing waves do propagate energy, although the extent of this energy transfer may vary. Understanding these concepts is essential for grasping wave behavior in physics. The discussion highlights the relationship between wavelength, speed, and energy propagation in standing waves.

Homework Statement



if [/B]wavelength changes does speed change
(in standing waves)

2. Homework Equations
velocity = wavelength * frequency

The Attempt at a Solution


i think it does because the wavelength changes so the speed will also change[/B]

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

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

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...

Thread 'A bead-mass oscillatory system problem'

Thread 'A bead-mass oscillatory system problem'

I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
