Answer:
Velocity of the emitted electrons increases
Explanation:
Velocity is directly proportional to frequency and this can be seen from the equation
v=fλ
Hence, if the frequency increases, the velocity is bound to also increase. Thus an increase in frequency as stated in the questions would definitely result to an increase in the velocity of the emitted electrons as seen from the equation above.
This condition is the cortical visual impairment. It is the leading reason of visual impairment in the west. It is due to a wide range of brain damage that affected the part for sense of vision. Such illness is characterized by unique visual responses to images.
