"Orange" color is most strongly reflected if it is illuminated perpendicular to its surface.
According to the question,
Refractive index, n = 1.33
Thickness, t = 233 nm
As we know,
t = λ /2n
or,
λ = 2tn
By putting the values, we get
= 2 x 233 x 10⁻⁹ x 1.33
= 620 nm.
Perpendicular lines are lines that intersect at an angle of 90 degrees. For example, line ST is perpendicular to line CD. Line ST is therefore perpendicular to line CD.
A perpendicular line is a line that meets or crosses another line and forms a right angle. The word "perpendicular" means "at right angles" because when two lines meet they form a right angle. Vertical lines can point in any direction. B. Up and down, sideways, sideways.
