Question
What is the velocity of light in a diamond if the
refractive index of diamond with respect to vacuum is 2.5?Solution
Refractive index of the diamond (µ )= 2.5 We know The velocity of light in vacuum (c) = 3 × 108 m/s To find the velocity of light in diamond (v) Now, µd = c/v => 2.5 = (3 × 108)/v => v = ( 3 × 108 )/2.5 = 1.2 × 108 m/s
In the question, two Quantities I and II are given. You have to solve both the Quantity to establish the correct relation between Quantity-I and Quantit...
[∛(3375/19683  )- ∛(125/1728  )  ] ÷ ∛(64/729)  = ? - 3/8Â
342 – 232 + 256 – 104 = ?
33 + ? = 40% of 1420
?2 = √20.25 × 10 + √16 + 32
If 28957.5 ÷ 268.125= 108, then 289.575 ÷ 2681.25 is equal to:
- Find the simplified value of the given expression.
(-8) x {15 - (-4) x (-5)} What should come in place of (?) question mark in the given expression.
(2/3 of 351) + (40% of 220) = ?
`(256/6561)(1/4) = ?`
