Answer:
The frequency decreases
Explanation:
In a wave, the relationship between wavelength and frequency is given by
![f=\frac{v}{\lambda}](https://tex.z-dn.net/?f=f%3D%5Cfrac%7Bv%7D%7B%5Clambda%7D)
where
f is the wave frequency
v is the wave speed
is the wavelength of the wave
In this problem, the wavelength of the wave is made longer (increased). From the formula above, we notice that the frequency is inversely proportional to the wavelength: therefore, as the wavelength increases, the frequency will decrease.
Answer:
the Architect should use {!$FieldType.lead.accessible} expression within the Visualforce page.
Explanation:
Visualforce is a framework that allows developers to build complex, user friendly interfaces that can be hosted primarily on the Lightning Platform
Controllers provide access to the data that should be displayed in a page, and can modify component behavior. a number of standard controllers are provided by The Lightning platform that contain functionality and logic that which are used for standard Salesforce pages
The Architect should Use the expression {!$FieldType.lead.accessible} within the Visualforce page.
Answer:
Intensity of the next bright fringe will remain same.
Explanation:
The question is based on Young's double slit experiment, since its about bright fringe, the interference here is constructive.
Young's condition for constructive interference is given by:
dsin![\theta = n\lambda](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20n%5Clambda%20)
where,
d = slits distance from eachother or width of the slits
= wavelength
n = interferance order
Also, we know that in Young's experiment, the fringe intensity is given by:
![I' = 4Icos^{2}\phi](https://tex.z-dn.net/?f=I%27%20%3D%204Icos%5E%7B2%7D%5Cphi%20)
where,
= phase difference
Therefore, in absence of phase difference i.e.,
, the intensity of the next bright fringe will not change and it will remain same.
