Are cosmic rays visible? Cosmic ray visual phenomena, or light flashes (LF), are spontaneous flashes of light visually perceived by some astronauts outside the magnetosphere of the Earth, such as during the Apollo program. Can you see cosmic rays on Earth? The problem is that right now, they just don’t have enough observations of the […]
What does half-life of radiation mean?
What does half-life of radiation mean? Half-life, in radioactivity, the interval of time required for one-half of the atomic nuclei of a radioactive sample to decay (change spontaneously into other nuclear species by emitting particles and energy), or, equivalently, the time interval required for the number of disintegrations per second of a radioactive … What […]

What direction do surface winds move in the Northern Hemisphere?
What direction do surface winds move in the Northern Hemisphere? The Coriolis effect makes wind systems twist counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. The Coriolis effect causes some winds to travel along the edges of the high-pressure and low-pressure systems. Why is Coriolis effect different in Southern Hemisphere? The reverse […]

What are three common types of optical instruments?
What are three common types of optical instruments? There are three main types of optical telescopes: refractive, reflective, and catadioptric. How are concave mirrors used in everyday life? Concave mirrors are used in reflecting telescopes. They are also used to provide a magnified image of the face for applying make-up or shaving. Concave mirrors are […]
What is the use of frequency table?
What is the use of frequency table? The frequency table records the number of observations falling in each interval. Frequency tables are useful for analyzing categorical data and for screening data for data entry errors. Note that we will refer to two types of categorical variables: Categorical and Grouping or Break. How do you estimate […]
