How Do You Calculate Logarithms with Base 2 and Perform Decibel Calculations?

AI Thread Summary
To calculate logarithms with base 2 using a simple calculator, one can use the change of base formula: log_a(x) = log_e(x) / log_e(a), substituting 'e' with '10' if preferred. For decibel calculations, understanding the relationship between logarithms and sound intensity is crucial, as decibels are a logarithmic unit. Online tutorials can provide valuable insights, but it's essential to ensure they cover base 2 logarithms specifically. A focused search using quotes can yield more relevant results. Mastering these concepts will enhance understanding of both logarithms and decibels.

logarithms and decibels please

Hi i need some good tutorials for the logarithmsI(especialy for logarithms with base 2)
and how i can calculate logarithms with base 2 when i have a simple calculator.
Also i need some decibel tutorials that can help me understand how i can perform calculations using decibels
 
Physics news on Phys.org
any kind of help please?
 
I did a google search on "logarithm tutorial" and got lots of good-looking hits. Do any of those help? (Just re-do the search, and include the quotes.)
 
Ok, I don't know about tutorials but log_a(x)=log_e(x)/log_e(a). If you don't like e you can substitute 10.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
