A photon detector captures a photon with an energy of 5.45 ✕ 10^−19 J. What is the wavelength, in nanometers, of the photon?
GarryVolchara [31]

Answer:

364 nm

Explanation:

The formula for the energy (E) of a photon in terms of its wavelength λ is

E = hc/λ

We can rearrange this formula to give

λ = hc/E

If E = 5.45 × 10⁻¹⁹ J, then  

\begin{array}{rcl}\lambda& = & \dfrac{6.626 \times 10^{-34} \text{ J$\cdot$s} \times 2.998 \times 10^{8}\text{ m$\cdot$ s}^{-1}} {5.45 \times 10^{19} \text{ J}}\\\\& = & 3.64 \times 10^{-7} \text{ m}\\& = & \textbf{364 nm}\\\end{array}\\

At 47c a gas has a pressure of 140kpa. The gas is cooled until the pressure decreases to 105kpa. If the volume remains constant,
IgorC [24]

Answer:

The final temperature is equal to 240 K or -33.15°C

Explanation:

Given that,

Initial temperature of the gas, T₁ = 47°C = 320 K

Initial pressure, P₁ = 140 kpa

Final pressure, P₂ = 105 kpa

We need to find the final temperature if the volume remains constant.  The relation between temperature and pressure is given by :

P\propto T

or

\dfrac{P_1}{P_2}=\dfrac{T_1}{T_2}\\\\T_2=\dfrac{P_2T_1}{P_1}\\\\T_2=\dfrac{105\times 320}{140}\\\\T_2=240\ K\\\\T_2=-33.15^{\circ} C

So, the final temperature is equal to 240 K or -33.15°C.
