Explain briefly how the sunshine duration is measured?
Sunshine duration is typically measured using a device called a sunshine recorder, which consists of a glass sphere that focuses sunlight onto a piece of paper. The recorder marks the duration of sunshine each day by burning a trace onto the paper. The length and intensity of the burn mark correspond to the amount of sunshine received.
What cause the amount of solar energy received in a particular area to change throughtout the year?
The amount of solar energy received in a particular area changes throughout the year mainly due to the Earth's tilt and its orbit around the sun. This results in varying angles of sunlight hitting the Earth's surface, affecting the intensity and duration of sunlight received in different seasons. Additionally, factors like cloud cover, atmospheric conditions, and geographic location also contribute to the variations in solar energy received.
How and why does solar altitude affect the intensity of solar radiation received at the Earth s surface?
The higher in the sky the sun is the more solar radiation received at the surface. This is because as the sun gets higher in the sky, there is less atmosphere blocking the sun's rays. Imagine the sun going through the atmosphere at a 90 degree angle. The thickness of the atmosphere let say is x thick. As the sun hit the surface at a lower angle, the thickness of the atmosphere has to go through more atmosphere to get to the surface. So the thicker atmosphere blocks more of the sun's rays.
The solar angle is a term that refers to the?
The solar angle refers to the angle between the sun and the horizon at a specific location. It is an important factor in determining the intensity of solar radiation received at that location, influencing factors such as heating and shading.
The earth's average distance from the sun is 1.50 1011m At this distance the intensity of radiation from the sun is 1.38 kWmThe earth's radius is 6.37106 What is the total solar power received?
To solve this problem, you can use the relation intensity equation:I = P/A, whereP represents Power andA represents Area.Rearranged, we have:P = IAWe are given Intensity I = 1.38 kW/m2 -> 1.38*103 W/m2, and Area A can be found withA = Pi*r2, wherer represents the radius of the earth,r = 6.37*106 mTotal solar power received daily by the earth is:P = I*Pi*r2= 1.38*103 * Pi * (6.37*106)2= 1.38*103 * 127.4114*1012Therefore, the total solar power received by the earth would be 1.76*1017 W.
What is Polar Radiation?
Polar radiation refers to solar energy received by the Earth's polar regions, particularly the North and South Poles. Due to the Earth's axial tilt and orbit, the polar regions receive sunlight at a lower angle compared to equatorial regions, leading to variations in the amount and intensity of solar radiation received throughout the year. This differential heating is a key factor influencing the climate and environmental conditions in polar areas.
How can one accurately measure sunlight in a given area?
One can accurately measure sunlight in a given area using a device called a pyranometer, which measures the total solar radiation received on a horizontal surface. This device can provide data on the intensity and duration of sunlight in a specific location.
What information is received from a seismograph?
A seismograph records the intensity and duration of seismic waves produced by earthquakes. This information helps seismologists determine the earthquake's location, magnitude, and depth.
What factors determine the extent of radiation damage?
The factors that determine the extent of radiation damage include the type of radiation, the dose received, the duration of exposure, the sensitivity of the tissues or organs affected, and the body's ability to repair damage. Additionally, factors such as the type of cells in the affected area and individual genetic variations can also influence the extent of radiation damage.
How can the radiation hurt you?
Exposure to high levels of radiation can damage cells in your body, leading to radiation sickness, cancer, or other health issues. The extent of harm depends on the type of radiation, dose received, and duration of exposure. Protective measures and adherence to safety guidelines can help minimize the risks of radiation exposure.
What is the difference between fluence and flux in the context of radiation measurement?
Fluence refers to the total number of particles passing through a unit area, while flux is the rate at which particles pass through a unit area. In radiation measurement, fluence measures the total amount of radiation received, while flux measures the intensity or flow rate of radiation at a specific point.

This results in varying angles of sunlight hitting the Earth's surface, affecting the intensity and duration of sunlight received in different seasons. Additionally, factors like cloud cover, atmospheric conditions, and geographic location also contribute to the variations in solar energy received.
What three factors that influence the amount of solar radiation?
The three main factors that influence the amount of solar radiation received at a location are the angle of incidence of the sunlight, the length of the day, and atmospheric conditions like cloud cover or air pollution. These factors affect how much sunlight reaches the Earth's surface and can impact the intensity of solar radiation.
Why do the regions receive less solar radiation than the equatiorial regions of the earth?
Regions away from the equator receive less solar radiation because the angle at which the sunlight strikes the Earth's surface is more oblique, spreading the energy over a larger area. This reduces the intensity of solar radiation received compared to the more direct and concentrated sunlight at the equator.
What are the ratings and certificates for Intensity - 1997 TV?
Intensity - 1997 TV is rated/received certificates of: Argentina:16 Australia:R
How does radiation damage human tissue?
Radiation exposure occurs from medical equipment, ultraviolet radiation from the sun and small but steady radiation from cell phones, microwaves and electrical towers. It damages human tissue by leaving the cells unstable, which can lead to cancer.
