{'transcript': "we have than the prime Minus Lambda. It was H over M C. Times one minus go side now disease head on conditions. So it's Cara's backwards. So 180 degrees Lambda equals C over F prime minus land I c over f It was come on to age over m E C. So we find one of our f Brian minus one where f it was okay to age over m E C Square. Mhm. Yeah. Now, that's what this x so we have. Actually, that's right. X equals to age. No, not too, Yeah. H f over m e c Square. So basically what we're trying to do is we're trying to do f over f prime minus one. It was to HF over m e c squared equals X. So we have f prime equals f over one plus two x now kind of big energy is H f minus. F prime equals H f. Times one minus 1/1 plus two X equals. So from here we find that k equals to h f X over one. Thus, two x"}
