Answer:
Obtuse
Explanation:
154 is larger then 90 (90 is a right angle)
if it was lower then 90 it would be accute
The minimum number of photons of green light that can be detected by the human eye is 6.
Given that;
E = nhc/λ
E = energy of the photon =
J
n = number of photons = ?
h = Planks constant =
Js
c = speed of light =
m/s
λ =
m
Making number of photons the subject of the formula;
n =
n = 6 photons
