The value of Planck's constant is

Options

A. `6.6 xx 10^(-32) g//m^(2)`s
B. `6.6 xx10^(-34) kg//m^(2)//s^(-1)`
C. `6.6 xx 10^(-33) kg//m//s^(-1)`
D. `6.6 xx 10^(-34) g//s^(-1)`

Answer

To find the value of Planck's constant, we can follow these steps:

### Step 1: Understand the relationship between energy and frequency
Planck's constant (h) is derived from the equation that relates the energy (E) of a photon to its frequency (ν):
\[ E = hν \]
This equation shows that the energy of a photon is directly proportional to its frequency.

### Step 2: Identify the value of Planck's constant
From the equation, we can isolate Planck's constant (h):
\[ h = \frac{E}{ν} \]
However, we already know the value of Planck's constant from established scientific data.

### Step 3: State the value of Planck's constant
The value of Planck's constant is:
\[ h = 6.626 \times 10^{-34} \text{ joule seconds} \]

### Step 4: Choose the correct option
If presented with multiple-choice options, we would select the one that states:
\[ 6.626 \times 10^{-34} \text{ joule seconds} \]

### Final Answer
The value of Planck's constant is \( 6.626 \times 10^{-34} \text{ joule seconds} \).
