@ sakshi
what u need to understand in this case is that continious spectrum is besically a emission spectrum with continnum wavelength , that means all the colours will be appear without any gap in a constant manner , and their wavelength will have a constant diffrence between them .
spectrum is besically a band of colours which will be obtained by any body which emits the radiation .
IN CONTINIOUS SPECTRUM WE GET DIFFRENT COLOURS IN SUCH A WAY THAT THEY SEEMS TO BE MERGE WITH ONE ANATHOR .
but the main thing is that their wavelength needs to have a constant diffrence within them and not variable .
FOR EXAMPLE
WHEN A WHITE LIGHT GET DISPERSED IN A PRISM , WE GET A BAND OF COLOURS , TAHT IS CALLED AS CONTINIOUS SPECTRUM .
U CAN ALSO TAKE THE EXAMPLE OF RAINBOW , THAT IS ALSO A GOOD EXAMPLE .
HOPE IT CLEARS YOUR DOUBT
IF SO, THEN PLZZ APPROVE MY ANSWER .
ALL THE BEST ..
