The answer is "B) Most species names are written in Swedish because Linnaeus was Swedish." Actually most if not all names in the Modern System of Taxonomic Classification are in Latin.
The formula for wave motion is speed of wave equals frequency times wavelength.v = f lambdarearrangingf = v/lambdaf = 0.6/0.02 = 60/2 = 30Hz, or cycles per second.
To solve this problem we will apply the concepts given by the principles of superposition, specifically those described by Bragg's law in constructive interference.
Mathematically this relationship is given as

Where,
d = Distance between slits
= Wavelength
n = Any integer which represent the number of repetition of the spectrum

Calculating the value for n, we have
n = 1

n=2

n =3

Therefore the intensity of light be maximum for angles 23.3° and 52.28°
Answer:
Explanation:
In closed organ pipe notes with odd harmonics are produced and in open organ pipe notes with all odd and even harmonics are produced. notes with frequencies 600, 800 and 1000 Hz are produced. These are 3 , 4 and 5 times 200 Hz. ie both odd and even times of 200 . So fundamental frequency appears to be 200 Hz. There is no note available between 800 and 1000. It also indicates that 200 Hz is the fundamental frequency and the pipe is open at both ends.
