What is the amount of energy for a photon that has a 125 cm wavelength

Lera25 [3.4K]

Answer:

1.59 x 10⁻²⁵ J.

Explanation:

The energy of a photon is calculated Planck - Einstein's equation:

E = h ν , where

E is the energy of the photon,

h is Planck's constant (h = 6.626 x 10 ⁻³⁴ J.s)

ν is the frequency of the photon

There is a relation between the frequency (ν ) and wave length (λ).

λ.ν = c,

where c is the speed of light in vacuum (c = 3 .0 x 10 ⁸ m/s).

λ = 125 cm = 1.25 m.

Now, E = h.c/λ.

∴ E = h.c/λ = (6.626 x 10 ⁻³⁴ J.s) (3 .0 x 10 ⁸ m/s) / (1.25 m) = 1.59 x 10⁻²⁵ J.

1. 2.0 mL/s x 4.0 hrs = ? L How do you do this conversion problem

Phantasy [73]

Answer:

29 L.

Explanation:

Hello!

In this case, considering that we are performing a conversion by which the time should be cancelled out to obtain liters, we first need to convert the seconds on bottom to hours and then the volume on top to liters, just a shown down below:

$2.0\frac{mL}{s} *\frac{1L}{1000mL} *\frac{3600s}{1hr}*4.0hr\\\\=28.8L$

Which turns out 29 L with 2 significant figures.

Best regards!
