The wavelength of a particular color of violet light is 417 nm. The energy of this wavelength of light is

E = 4.7 x Joules

Explanation:

Solution:

The wavelength of a particular color of violet light = 417 nm

What is the energy = ?

In order to calculate energy, we will use the following formula:

E = hf

where, f = frequency = 1/wavelength = c/λ

where c = speed of light = 299 792 458 m / s or 3 x m/s

where h = Plank's constant = 6.62x kg / s

So,

λ = 417 nm

1 nm = m

so,

λ = 417 x m

Now, just plug in the values to calculate the energy of this wavelength of light.

E = hc/λ

E = ( 6.62x ) (299 792 458) / (417 x )

E = 0.047 x

E = 4.7 x Joules

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
