The correct answer is "wavelength".
In fact, this is exactly the definition of wavelength: in a wave, the wavelength is defined as the distance between two succesive crests or two successive troughs, therefore the correct answer is
D) wavelength.
Answer:
The correct answer is B-25 V
Explanation:
We apply Ohm's Law, according to which:
V = i x R
V = 5A x 5Ω
V= 25 V
Being V the potential difference whose unit is the VOLT, i the current intensity (Ampere) and R the electrical resistance (ohm)
Answer:
The correct option is;
c. Temperature and color
Explanation:
Based on Wien's Law which can be presented mathematically as follows;
The wavelength of the peak of the blackbody curve tells the temperature and color.
An example is the Sun that has a temperature of 5800 K, hence the peak wavelength is given by 
= 500 nano-meter from which the color can be deduced as 500 nano-meter is the wavelength of yellow light.
