ଦୈର୍ଘ୍ୟ 10^-10 ମିଟରର ଫଲଟନର ଶକ୍ତି (h = 6.626 x 10^-34 Js, c = 3 x 10^8 ms^-1) (A) 6.626 x 10^-34 J (B) 6.626 x 10^-34 J (C) 6.626 x 10^-34 J (D) 6.626 x 10^-34 J (NEET 2015)
ଉତ୍ତର (A) ଅଟେ।
ଫଲଟନର ଶକ୍ତି E = hc/λ ଦ୍ୱାରା ଦିଆଯାଏ, ଯେଉଁଠାରେ h ହେଲା ପ୍ଲାଙ୍କର ଧରଣ ସଂଖ୍ୟା, c ହେଲା ଆଲୋକର ଗତି, ଏବଂ λ ହେଲା ଫଲଟନର ଦୈର୍ଘ୍ୟ। ଏଠାରେ, h = 6.626 x 10^-34 Js, c = 3 x 10^8 ms^-1, ଏବଂ λ = 10^-10 ମିଟର। ଏହି ମୂଲ୍ୟଗୁଡ଼ିକୁ ସୂତ୍ରରେ ବ୍ୟବହୃତ କରିବାରେ ଆମେ E = 6.626 x 10^-34
