I don't think the magnitude of the current is. But there is a definite wavelength of
incident light where photo-current suddenly begins ... longer wavelengths produce
no photo-current at all, no matter how bright the light is. Einstein was awarded his
first Nobel Prize for the explanation of why that happens.
yes
Yes, definitely . For the given metal of particular work function, decrease in wavelength of the incident beam increases the maximum value of kinetic energy with which the photoelectrons are emitted, but the photoelectric current remains the same, stoppage voltage increases.
The equation relating the velocity, wavelength and frequency of an electromagnetic wave is given byv=f λwhere v - velocity of the em wavef - frequency of the em wave andλ - wavelength of the em wave------------------------------------------------------------------------------------------------It is so important to know that velocity of light depends on the nature of the medium and does not depend on the wavelength.
It splits into its constituent colours according to wavelength as VIBGYOR
The focal length does not depend upon the wavelength or the frequency so it remains unaffected.
Simply put yes. Color is determined by our interpretation of light that is receive in our eyes. Colors can be created in various ways with various combinations of specific wavelengths of light. In addition each color can be represented by an individual wavelength of light. Therefore it is dependent on wavelength.

No.
Yes.
the amount of scattering does not depend on wavelength..
yes in some cases but that is depend on the wavelength/nature of that light.
This phenomenon is called diffraction. when light is incident on the opaque substances having width comparable to wavelength of light then light bend.
Different wavelengths of light have different colors.
To function efficiently the eye needs bright light. For maximum efficiency the eye needs light to be at a wavelength of 0.555um. The eye can perform efficiently in the dark at a wavelength of 0.510um, but there is a weakness in color.
