To find that sunlight is mixture of seven colours we can use Newton's disc it contains seven colours of rainbow and when we rotate it very fast then we can clearly see the white colour and then we can say that sunlight is mixture of seven colours of rainbow

[@saiswaroopajena3736]

Sunlight -white because white light produces the mixture of different colours Example -rainbow

I have a doubt... Agar ek object ko phele se hi upside down krke rakha hua ho to concave mirror ki wajah se screen me woh object ka image seedha aayega kya ?? And jo movies screen me dekhte hain hum wo kya phele se hi undide down hota hai projector me ??? Jisse hi hame movie seedha dikhta hai ????
