Answer:

As the wavelength of an electromagnetic wave _decrease__ the frequency of the wave _increase_______.

Explanation:

What is the relationship between frequency and wavelength?

Wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.

That number, also known as the frequency, will be larger for a short-wavelength wave than for a long-wavelength wave. The equation that relates wavelength and frequency is:

V= fλ

where v= velocity

f= frequency

λ = wavelength

⇒ f = v/λ

also f ∝ 1/λ

For electromagnetic radiation, the speed is equal to the speed of light, c, and the equation becomes:

C= fλ

where c= Speed of light

f= frequency

λ = wavelength

⇒ f = v/λ

also f ∝ 1/λ

Whenever you work a physics problem you should get into the habit of thinking about whether the answer is physically realistic.

Marta_Voda [28]

Answer:

Yes, the answer on <em>how far off the ground a typical truck is happens to be</em> physically realistic.

Explanation:

This concept could be explained with when someone is viewing a picture from a particular distance. The farther the person is from the picture, the smaller the details of the picture and the higher they picture would be unappriciated and vice versa.

Likewise the small truck on ground. <em>The distance off ground the truck is being viewed, the smaller the truck would become.</em>

In a double-slit experiment, if the central diffraction peak contains 13 interference fringes, how many fringes are contained wi

Ronch [10]

Answer:

Explanation:

Width of central diffraction peak is given by the following expression

Width of central diffraction peak= 2 λ D/ d₁

where d₁ is width of slit and D is screen distance and λ is wave length.

Width of other fringes become half , that is each of secondary diffraction fringe is equal to

λ D/ d₁

Width of central interference peak is given by the following expression

Width of each of bright fringe = λ D/ d₂

where d₂ is width of slit and D is screen distance and λ is wave length.

Now given that the central diffraction peak contains 13 interference fringes

so ( 2 λ D/ d₁) / λ D/ d₂ = 13

then ( λ D/ d₁) / λ D/ d₂ = 13 / 2

= 6.5

no of fringes contained within each secondary diffraction peak = 6.5
