Jawaban:

Panjang gelombang foton setelah hamburan

begin mathsize 14px style lambda apostrophe minus lambda equals fraction numerator h over denominator m subscript 0 c end fraction open parentheses 1 minus cos theta close parentheses lambda apostrophe minus 20 A with dot on top equals fraction numerator 6 comma 62 cross times 10 to the power of negative 34 end exponent over denominator 9 comma 1 cross times 10 to the power of negative 31 end exponent.3 cross times 10 to the power of 8 end fraction open parentheses 1 minus cos 53 degree close parentheses lambda apostrophe minus 20 A with dot on top equals 0 comma 242 cross times 10 to the power of negative 11 end exponent open parentheses 1 minus 0 comma 6 close parentheses lambda apostrophe minus 20 A with dot on top equals 0 comma 9 cross times 10 to the power of negative 10 end exponent lambda apostrophe minus 20 A with dot on top equals 0 comma 9 A with dot on top lambda apostrophe equals 20 comma 9 A with dot on top end style
