# Question: What does φ mean in physics?

Contents

The lowercase letter φ (or often its variant, ϕ) is often used to represent the following: Magnetic flux in physics. The letter phi is commonly used in physics to represent wave functions in quantum mechanics, such as in the Schrödinger equation and bra–ket notation: . The golden ratio.

## What is phi equal to in physics?

Phi ( Φ = 1.618033988749895… ), most often pronounced fi like “fly,” is simply an irrational number like pi ( p = 3.14159265358979… ), but one with many unusual mathematical properties. Unlike pi, which is a transcendental number, phi is the solution to a quadratic equation.

## What is the value of ϕ?

The formula basically says that the value of Φ(n) is equal to n multiplied by-product of (1 – 1/p) for all prime factors p of n. For example value of Φ(6) = 6 * (1-1/2) * (1 – 1/3) = 2.

## What do you mean by phi?

Phi, pronounced FY or sometimes FEE in English, and in modern Greek, is the 21st letter of the Greek alphabet. In modern Greek, it represents, a voiceless labiodental fricative. In Ancient Greek it represented, an aspirated voiceless bilabial plosive. In the system of Greek numerals it has a value of 500 or 500,000.

## Where is phi used in physics?

The convention in physics is to use phi as the azimuthal angle (from the x-axis). One of the dihedral angles in the backbones of proteins in a Ramachandran plot. Internal or effective angle of friction.

## Where is phi found?

In the world of mathematics, the numeric value is called phi, named for the Greek sculptor Phidias. The space between the collumns form golden rectangles. There are golden rectangles throughout this structure which is found in Athens, Greece.

ϕ(84)=24.

## How do you get phi?

Phi is most often calculated using by taking the square root of 5 plus 1 and divided the sum by 2:√5 + 1. BC = √5.DE = 1.BE = DC = (√5-1)/2+1 = (√5+1)/2 = 1.618 … = Phi.BD = EC = (√5-1)/2 = 0.618… = phi. •May 13, 2012

## What is PHI medical?

PHI stands for Protected Health Information. The HIPAA Privacy Rule provides federal protections for personal health information held by covered entities and gives patients an array of rights with respect to that information.

## What are some examples of PHI?

Examples of PHIPatient names.Addresses — In particular, anything more specific than state, including street address, city, county, precinct, and in most cases zip code, and their equivalent geocodes.Dates — Including birth, discharge, admittance, and death dates.Telephone and fax numbers.Email addresses. •11 Jan 2015

## How is PHI found?

Phi can be defined by taking a stick and breaking it into two portions. Phi is closely associated with the Fibonacci sequence, in which every subsequent number in the sequence is found by adding together the two preceding numbers. This sequence goes 0, 1, 1, 2, 3, 5, 8, 13, 21, 34 and so on.

## Why is PHI so important?

PHI is important to individuals and valuable to hackers which makes it vital for organizations to protect. HIPAA lays out all the requirements and safeguards that should be put in place so that each persons identifiable health information is kept secure from cyber criminals.

## What numbers make up φ 12?

## Is 1 relatively prime to any number?

Any two prime numbers are always relatively prime. For example, in 19 and 17 the only common factor is 1 and they are prime numbers too. A prime number is relatively prime with any other number because prime numbers are the numbers that can be divided by one or themselves.
