The correct answer of this question is : A) Radio waves have longer wavelengths, lower frequency, and lower energy than ultraviolet waves and x-rays.
EXPLANATION :
Before going to answer this question, first we have to know the electromagnetic spectrum.
Electromagnetic spectrum is the arrangement of electromagnetic waves in the ascending order of frequency or descending order of wavelength.
When the waves are arranged in the ascending order of their frequency, then perfect order is given below as such -
Radio wave < Micro wave < Infrared wave < Visible light < U.V ray< X-ray < Gamma ray .
Hence, we see that radio wave has the least frequency, and gamma ray has the most frequency.
We know that wavelength and frequency are inversely are inversely proportional to each other. Hence, radio wave has more wavelength and less frequency.
The wave having more frequency is more energetic. Hence, gamma is more energetic and radio wave is less energetic .
Answer:A language is a structured system of communication. Language, in a broader sense, is the method of communication that involves the use of – particularly human – languages. The scientific study of language is called linguistics
Explanation:
You are asked to calculate an object's velocity.
In order to do so, you must know the object's speed and the direction
in which it's moving, or you must have other information that makes it
possible for you to calculate its speed and direction.
Answer:
3-year = 6.33%
5-year = 7%
Explanation:
Yield in security = Risk free rate + Maturity risk premium + Inflation premium + Liquidity premium + Default risk premium
Maturity risk premium is given as 0
Yield on 3-year treasury securities is 2 + [(3.5 + 3.5 + 6) / 3] + 0
= 6.33%
Yield on 5-year treasury securities is 2 + [(3.5 + 3.5 + 6 + 6 + 6) / 5] + 0
=7%
