Answer:
Periodic
Explanation:
A periodic (or repetitive) wave has continuously repeating pattern with characteristics such as amplitude, wavelength and frequency. In a periodic wave, a series of pulses that are evenly timed would be created. In other words, the wave pattern in a periodic wave repeats at regular intervals.
An example of a periodic wave is the sound from the strings of a violin.`
The diagram is labelled to DRAW the RESULTANT wave and LABEL the areas of interference with CI, DI and/or points of TDI.
<h3>What is refraction?</h3>
When a light ray falls on the interface of two medium like air and water, then the portion of light is reflected and another portion of the light is refracted into the water medium. The angle of incidence is equal to the angle of reflection but the angle of incidence is larger then the angle of refraction.
Open the attached file. It shows 2 waves (a blue one and an orange one) that are moving through the same medium at the same time.
Thus, the diagram is labelled.

Answer:
Explanation:
3.75 * 10^-7
=3.75 * 1/10^7
=3.75/10000000
=3/800000000
any base which has it's power negative do it's reciprocal then the power will be positive.
Answer:
Voltmeter
Explanation:
A voltmeter is usually defined as an instrument that is commonly used to measure the electric potential difference acting between the two ends of a circuit. The unit of voltmeter is volts. Here, connections are made in parallel arrangement.
An ammeter is a device that is commonly used to measure the amount of flowing current within a circuit. The unit of current is in terms of amperes (A). Here, connections are made in series.
A voltmeter is usually comprised of high internal resistance in comparison to an ammeter because a high internal resistance results in the heating up of the battery and subsequent dropping its voltage and after the equipments are being cuts off, it leaves behind certain amount of energy.
