I've been sick recently so I missed out on the lessons :/
Thanks if you answer my Q
Thanks if you answer my Q
-
(6-10/3)/(4--5) =
(8/3)/9 = 8/27
(8/3)/9 = 8/27
-
the formula for gradient is y2-y1/x2-x1 or simply rise/run
(6-10/3)/4-5
(2 2/3)/-1
m= -2 2/3
(6-10/3)/4-5
(2 2/3)/-1
m= -2 2/3

Use a hydrogen wavelength calculator
-
m = ( 6 - 10/3 ) / ( 4 + 5 )
m = (9/3) / 9
m = 1/3
m = (9/3) / 9
m = 1/3
