Yes, but it's a null vector .So,no vector can have a component at right angle to itself unless it is a zero vector.
Answer:
The distance from the central bright spot are
and
.
Explanation:
Given that,
Wavelength = 490 nm
Distance y= 15 mm
Length L=1.6 m
New wavelength = 670
We need to calculate the distance from the central bright spot
Using formula of distance


Put the value into the formula



We need to calculate the distance from the central bright spot for new wavelength
Using formula of distance

Put the value into the formula



Hence, The distance from the central bright spot are
and
.
Answer:
this happens because there is gravitational force acting upon it.
Y, bc the height of the bounce back is higher than x
