You can write him letters, which is the traditional way, but there are also ways to email him and do video chats with him as well nowadays.
Actually, different physical quantities are measured in different ways. For example, it is quite different to measure the diameter of a table, than to measure the capacitance of a capacitor, the frequency of a sound, etc. Each one requires different methods. Even for the same quantity there might be differences, for example, low-frequency and high-frequency sounds, and ultrasounds (a frequency so high that we can't hear it), may require different methods.

There are several ways to calculate the frequency of light emitted or absorbed by different chemicals, and they depend on what you already know. For example, if you know the energy of the particle, then you can calculate frequency from E = planck's constant x frequency and solve for frequency. If you happen to know the wavelength, then you can use C = wavelength x frequency and solve for frequency (where C = speed of light).
Animal hearing is different to human hearing in various ways. The main difference is that animals have a high frequency range as opposed to the human ear.

These are just different ways of saying the same thing.
they are the same but just with different ways of saying it.
