What is the formula to find real depth?
The formula to find real depth, particularly in the context of underwater or geological measurements, often involves using the principle of refraction. A common formula used is ( D = \frac{h}{\cos(\theta)} ), where ( D ) is the real depth, ( h ) is the apparent depth observed, and ( \theta ) is the angle of incidence. In some contexts, additional factors such as the refractive index of the medium may also be considered.
What is the index of refraction of a refractive medium if the angle of incidence in air is A degrees and the angle of refraction is B degrees?
The index of refraction ( n ) of a refractive medium can be calculated using Snell's Law, which states that ( n = \frac{\sin(A)}{\sin(B)} ), where ( A ) is the angle of incidence in air and ( B ) is the angle of refraction in the medium. Since the index of refraction of air is approximately 1, this formula directly provides the refractive index of the medium. Simply plug in the values of ( A ) and ( B ) to find the result.

What is Modulation index formula in Frequency modulation?
The modulation index formula in frequency modulation (FM) is given by the equation: β = Δf / fm, where β is the modulation index, Δf is the peak frequency deviation, and fm is the modulating frequency. Modulation index indicates how much the carrier frequency is being varied by the modulating signal in FM.

What do you mean by depth of modulation index?
The depth of modulation index refers to the extent to which a carrier signal is varied by a modulating signal in amplitude modulation (AM). It is typically expressed as a percentage and indicates how much the amplitude of the carrier wave changes in response to the modulating signal. A modulation index of 100% means full modulation, where the carrier's amplitude varies completely with the modulating signal. Values above 100% can lead to distortion and over-modulation, impacting the quality of the transmitted signal.
When modulation frequency is doubled modulation index also doubled in case of FM or pm or am?
In Frequency Modulation (FM), if the modulation frequency is doubled, the modulation index does not necessarily double; it depends on the amplitude of the modulating signal. In Amplitude Modulation (AM), the modulation index is defined as the ratio of the peak amplitude of the modulating signal to the carrier amplitude, so it remains unchanged with varying modulation frequency. For Phase Modulation (PM), similar to FM, the modulation index is influenced by the amplitude of the modulating signal and does not inherently double with the modulation frequency. Thus, modulation frequency and modulation index are not directly linked in this way for FM, PM, or AM.
