# I'm New And I Have A Couple Questions For Grade 12 Physics

• livvy
In summary, the question is asking for the speed of sound in steel, given a frequency of 442 Hz and a measured wavelength of 11.66 m. The relationship between speed, frequency, and wavelength for any wave is represented by the equation speed = frequency x wavelength. So, to find the speed of sound in steel, we can use this equation and plug in the given values. Remember to show your attempt at solving the problem before asking for help. Good luck!

okay so here's the question...can anyone figure it out... the question is... Sound with a frequency of 442 Hz. travels through steel. A wavelength of 11.66 m is measured. Find the speed of the sound in steel. Please help...i really need some direction

Welcome to the forum. We do expect you to show us some attempt to solve a problem yourself, and then we will help you. Here is a hint:

What is the relationship between speed, frequency, and wavelength for any wave?

so is that equation Speed=frequency x wavelenth?

Yes, that's exactly what you need to do.

test. It looks like youre on the right track now
