The wavelength (λ), speed (c) and the frequency (ν) of a wave are related as:
ν = c/λ -----(1)
The speed of the waves is a constant in vacuum i.e. it remains at 3*10⁸ m/s. therefore, it will not change with changes in wavelength or frequency.
Let us consider:
ν1 = initial frequency and λ1 = initial wavelength
ν2 = final frequency and λ2 = final wavelength = 2(λ1)
based on equation (1) we have:
ν1/ν2 = λ2/λ1 = 2(λ1)/λ1 = 2
therefore: ν2 = 1/2(ν1)
The frequency will get reduced by one-half as the wavelength doubles.

Explanation:
The trend in the electronic configuration on the periodic table follows a definite pattern because the arrangement of elements on the table is based on the periodic law.
The periodic law states that "The properties of elements are a function of their atomic number".
- Elements in the same horizontal period have increasing number of valence electrons.
- The number of valence electrons stays the same down a group.
- Groups 1 and 2 are known as the s-block and electrons are added to the s-orbitals for them.
- Groups 3 to 12 is the transition block and electrons the valence d-orbital.
- Groups 3 through 18 is the p-block where the valence shell is the p-orbital.

Answer:
dollars each person will receive.
Explanation:
Number of people in which 1 mole of pennies is distributed = 250 million =
250 million = 
persons
Number of pennies in 1 mole = 
Pennies per person:
1 penny = 0.01 $
dollars each person will receive.
