How Do You Calculate the Frequency of Radio Waves with a Wavelength of 100mm?

AI Thread Summary
To calculate the frequency of radio waves with a wavelength of 100mm, the relationship between speed, wavelength, and frequency is essential, expressed as wave speed = frequency * wavelength. Since radio waves are electromagnetic waves, they travel at the speed of light, approximately 3 x 10^8 m/s. Using the formula, the frequency can be calculated by rearranging it to frequency = wave speed / wavelength. For a wavelength of 100mm (0.1m), the frequency is 3 x 10^8 m/s divided by 0.1m, resulting in a frequency of 3 x 10^9 Hz. Understanding the speed of light as the relevant speed is crucial for accurate calculations.

How are speed, wavelength, and frequency related?
 


wave speed = frequency * wavelength

wave speed = frequency * wavelength
Good. That's all you need to solve for the frequency.
 


ya but which speed do i use?

Both light and radio waves are examples of electromagnetic waves, which have the same speed in a vacuum.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
