    Yes, intensity and frequency are very different terms.

    Intensity is just the brightness. Like white light can be of low intensity or high intensity. Intensity is just the measure of brightness. A same coloured light can have different intensity. Intensity changes means brightness changes. But the colour of the light remains same. But frequency is not the measure of brightness. If there is a change in frequency the colour of the light will be changed. Like red light has low frequency and violate has high frequency. So easily you can understand what is the difference. Note -ย wave length is inversely proportional the frequency. Like Red light has bigger wave length than violate.

    Yes Sweta they are different

    eduncle-logo-app

    Intensity is number of Photon incident per unit time.

    eduncle-logo-app

    Frequency you can understand as 1 Photon.

    eduncle-logo-app

    This is simple Idea based on particle properties of light

    eduncle-logo-app

    ok thanks

    eduncle-logo-app

    sir why u often used to delete the chats

    eduncle-logo-app

    If you feel that my answer helps you then please.. please accept my answer.

    eduncle-logo-app

    I request you please dear ๐Ÿ™

    eduncle-logo-app

    sir I mark your answer

    eduncle-logo-app

    it's really helps sir

    eduncle-logo-app

    If someone comments help you in understanding the concept then only mark it thankyou ๐Ÿ™.

    eduncle-logo-app

    priyanshu sir comment also help me

    eduncle-logo-app

    wherever I see thanku I mark that

    eduncle-logo-app

    but in your case I used to write thanku

    eduncle-logo-app

    I donot know what's the prob hete

    eduncle-logo-app

    ok next time I take care of this

    eduncle-logo-app

    ok I literally donot know about this

    eduncle-logo-app

    sir next time only one thanku

    eduncle-logo-app

    please understand if you don't mark thankyou I feel demotivated feeling that my comment doesn't help you so I deleted ๐Ÿ˜”

    eduncle-logo-app

    sir there is one confusion that your are a male teacher or female teacher

    eduncle-logo-app

    Male teacher ๐Ÿ˜‚

    eduncle-logo-app

    because I somewhat get confused in writing sir or mam

    eduncle-logo-app

    It's ok no problem ๐Ÿ‘. I am here to solve your problem to the best of my knowledge. That's it

    eduncle-logo-app

    actually someone wrote mam so that why

    eduncle-logo-app

    sir can u plz send me 1,1dimetgyl cyclohexane chair to newman

    eduncle-logo-app

    ok

    eduncle-logo-app

    I have drawn like this

    eduncle-logo-app

    See after 20 minutes. I guarantee it will clear your doubts

    eduncle-logo-app

    ok

    eduncle-logo-app

    Did you get this now

    Priyanshu kumar best-answer

    yes shweta these are different

    eduncle-logo-app

    intensity is no of photon incident on a metal surface per unit area per unit time

    eduncle-logo-app

    In photoelectric effect you read all these

    eduncle-logo-app

    and frequency you know... the number of waves that pass a point in space during any time interval, usually one second. We measure it in units of cycles (waves) per second, or hertz

    eduncle-logo-app

    In photoelectric effect you read that however more intense the light is if the frequency is light is more than or equal to threshold frequency then only ejection of electrons is possible

    eduncle-logo-app

    hope you got it now๐Ÿ˜Š

    eduncle-logo-app

    yes sir now plz tell me relation between intensity and kinetic energy

    eduncle-logo-app

    yes wait typing shweta

    eduncle-logo-app

    ok ok

    eduncle-logo-app

    shweta you read all these in photoelectric effect....intensity and frequecy relation, kinetic energy and frequecy relation

    eduncle-logo-app

    sry sir

    eduncle-logo-app

    I have read

    eduncle-logo-app

    sir

    eduncle-logo-app

    you read these that KE is directly proportional to frequency but independent of intensity

    eduncle-logo-app

    yes sir

    eduncle-logo-app

    In photoelectric effect graph on these things are given

    eduncle-logo-app

    ok

    eduncle-logo-app

    thanks๐Ÿ˜Š

    eduncle-logo-app

    you are welcome...๐Ÿ˜Š...you know what happen while typing if reply comes then the whole written things get deleted

    eduncle-logo-app

    Haan I know this but aaj bhool gyi thi

    eduncle-logo-app

    ok ok๐Ÿ˜€๐Ÿ˜Š

    eduncle-logo-app

    again sir

    eduncle-logo-app

    m typing sir

    eduncle-logo-app

    is aap ki problem hai JB koi likhta TB unko mention krna chahiye that he or she is typing

    eduncle-logo-app

    app*

    eduncle-logo-app

    yes...then there is no problem from any side...

    eduncle-logo-app

    yes sir
