It will be around 1.6metres
hope it helps
Answer:
Step-by-step explanation:
Angle of incidence is the angle formed at the point of incidence between the incident ray and the normal. Angle of refraction is the angle formed between the refracted ray and the normal .
According to Snell's law,
Here, are indexes of incidence and refraction.
are angles of incidence and refraction.
Given:
On putting these values in the Snell's law, we get
4x is less than 4 when x is less than 1
<h3>How to determine when is 4x < 4 ?</h3>
The given statement is
when is 4x < 4
This means that
when is 4x less than 4
So, we have
4x < 4
Divide both sides of the inequality by 4
4x/4 < 4/4
Evaluate the quotient
4x/4 < 1
Evaluate the quotient
x < 1
This means that 4x is less than 4 when x is less than 1

The Total Number of socks is 10 in all, bear in mind that there is no blue socks hence it will not add to the total amount of socks
<h3>Addition of Numbers</h3>
Note : 1 pais = 2 socks
Given Data
- Red Socks = 4 pairs = 4*2 = 8 socks
- 6 times as many pairs of blue socks = 0
- 1 as many pairs of white socks = 2 socks
The statement " 6 times as many pairs of blue socks" is equivalent to no socks, since we have no blue socks, hence 6*0 = 0
Let us find the total socks
= 8+0+2
= 10 socks
