The correct answer is visible light.
Hope this helps.
Answer:
0.98°
Explanation:
First we find the refracting angle of orange in water
Which is given as
စr= sin^-1. ( 1.456 sin60°/1.33)
= 71.2°
Then that of violet in water
စv=sin^-1. ( 1.468sin60°/1.342)
= 72.3°
So angle between boths colours is the difference
71.2- 72.3= 0.98°
It’s proportional to net force
Answer:
Frequency will not change.
Explanation:
As you know, Time period 'T' = 2π x √(L/g)
where,
L= the length of the pendulum
g= acceleration due to gravity
and Frequency 'f' is the reciprocal of period.f=1/T
From above, we can conclude that frequency is not dependent on mass.
It depends upon the acceleration due to gravity 'g' and the length of the pendulum 'L'
So, if a hole in the ball allowed water to slowly leak out, frequency would not change
