20. An architect is doing a survey using his Theodolite He lound out that he is standing 450 meters from the building and the building is 645 meters from the ground. What is the angle of elevation the architect must have absened from his surveying tool? Refer to Figure A as the illustration for the problem M 50.10° A 5097 Figures T 55.10 H.55.97​

Answer:

WAVELENGTH

Question: What is the wavelength of the wave with a frequency of 3x10^{9}3x10

9

Hz?

Formula: λ = ν/f

where; lambda (λ) = the wavelength of the wave

ν = velocity, or the speed of light c = 3x10^{8}3x10

8

m/s. and;

f = the frequency of the wave equals 3x10^{9}3x10

9

Hz or per second

Solution:

λ = ν/f = \frac{3x10x^{8} m/s }{3x10^{9}/s }

3x10

9

/s

3x10x

8

m/s

= 0.1 meters or 1x10^{8}1x10

8

nanometers

Definition of terms:

Wavelength - In Physics, a wavelength spatial period or distance between the periodic wave's highest p o i n t (adjacent crest). In other words in is the distance separating two consecutive p o i n t s of two waves.

Frequency - The frequency of the wave is the number of wave occurence per unit time, usually in seconds. Also measured in Hertz or Hz means per seconds 1\s.

Velocity - Pertains to the speed of the wave, usually light. The speed of light is equal to 3x10^8 meters per second.

Answer:

An architect is a person who plans, designs and oversees the construction of buildings.[1] To practice architecture means to provide services in connection with the design of buildings and the space within the site surrounding the buildings that have human occupancy or use as their principal purpose.[2] Etymologically, the term architect derives from the Latin architectus,[3] which derives from the Greek[4] (arkhi-, chief + tekton, builder), i.e., chief builder.[5]
