The frequency of the green light of the electromagnetic spectrum is 5.45 × 10¹⁴ Hz.
The green light is found in the visible region of the electromagnetic spectrum.
An Electromagnetic is a spectrum which is made up of all kind of wave is constitute and electric as well as magnetic field.
The green light which is the constituent of the white light fall under the visible region of the electromagnetic spectrum so it can have the frequency 5.45 × 10¹⁴ Hz.
This frequency is more than the infrared frequency but less than the ultraviolet frequency.

Volume of the original block (V) of length (l), width (w) and height (h) is given by the following equation
hence volume of original block, V = (6)(4)(10) =
Now say we cut this block in two equal parts, than the length of new block will be ; where as its width and height will be same as of original block i.e. 4 cm and 10 cm respectively.
So, Volume of half-block is ; or we can say that the volume of half-block is half that of orignal block.
Answer:
0.3 N
Explanation:
i = 400 A
B = 30 x 10^-6 T
L = 25 m
Force due the current carrying conductor placed in a magnetic field
F = B i L SinФ
where, Ф be the angle between length vector and magnetic field vector
F = 30 x 10^-6 x 400 x 25 = 0.3 N
It can dissolve many substances because 1. Polarity of water molecule. 2. Exceptional hydrogen bonding ability (Not in list)
0.29 m/s is the speed of this wave.
How can we determine a wave's speed?
Given: The wave's traveling wavelength is () = 35 cm
The wave's period (t) is 1.2 seconds.
The wave's frequency is 0.833 Hz.
We must ascertain a wave's wave speed.
Formula for wave speed is 35 x 0.833 (wavelength x frequency).
= 29.167 cm/sec
= 0.29 m/sec
As a result, the wave's speed is 0.29 m/s.
