Consider a wave with a wavelength = 2.5 cm that traveling at a speed of 15 m/s. (a) How long does it take for the wave to travel a distance of one wavelength? (b) How many wavelengths (or cycles) are completed in 1 second? (The number of waves or cycles completed per second is referred to as the wave frequency.) (c) If = 3.0 cm but the speed remains the same, how many wavelengths (or cycles) are completed in 1 second? (d) If = 1.5 cm and the speed remains the same, how many wavelengths (or cycles) are completed in 1 second? (e) What can you conclude regarding the relationship between wavelength and number of cycles traveled in one second, which is also known as frequency ()?
Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
Consider a wave with a wavelength = 2.5 cm that traveling at a speed of 15 m/s.
(a) How long does it take for the wave to travel a distance of one wavelength?
(b) How many wavelengths (or cycles) are completed in 1 second? (The number of waves or cycles
completed per second is referred to as the wave frequency.)
(c) If = 3.0 cm but the speed remains the same, how many wavelengths (or cycles) are completed in
1 second?
(d) If = 1.5 cm and the speed remains the same, how many wavelengths (or cycles) are completed in
1 second?
(e) What can you conclude regarding the relationship between wavelength and number of cycles
traveled in one second, which is also known as frequency ()?
Answer
a) To travel a distance of one wavelength it takes 0.00167 seconds
b) The no.of wavelengths that can be completed in 1 second is 599.99 (or) 600 cycles of wavelengths
c) If wavelength = 3.0 cm, the no.of wavelengths completed in 1 second = 500 cycles
d) If wavelength = 1.5 cm, the no.of wavelengths completed in 1 second = 1000 cycles
e) The relationship between wavelength and frequency, Frequency =
