Tag the questions with any skills you have. Your dashboard will track each student's mastery of each skill.
Which electromagnetic wave has the highest energy?
What happens to the frequency and wavelength if the energy of the wave decreases?
Radio waves, X-ray waves, and microwaves are detected to betravelling in a vacuum. If the waves have a wavelength of 2 x 103 m, 2 x 10-9m, 2 x 10-1 m respectively, which of the three travels the fastest?
An FM radio station broadcasts at 9.05 MHz (9.05 x 107 Hz).The radio wave travels at the speed of light, what is its wavelength?
A gamma ray with a frequency of 6.2 x 1019Hz is fired on an unknown object in space. The value of Planck’s constant is 6.626 x 10-34Js. How much energy does the wave carry?
What will happen if the antenna of the analog television is placed inside the house?
Which is NOT included in the group for radio communication?
Which causes sugar, water, and fat to vibrate at extremely high frequencies?
Which item must NOT be placed inside the microwave oven?
Which is the center of transmitting and receiving radio waves towards television and radio communication?
What form of electromagnetic radiation has the most energy?
Which is NOT a probable result of the human tissue’s exposure to ionizing radiation?
What does ionizing radiation remove from atoms?
What is the difference between ionizing and non-ionizing radiation?
How can we protect ourselves from harmful electromagnetic radiation?
A ray of light is incident on a surface at 330 from the normal. What will be the angle of reflected ray from the normal?
An incident light travels on a path shown in Figure 1. Which of the following paths is most likely to be taken by the reflected light?
It is a position where an object should be placed when in front of a concave mirror so that it reflects the image with the same size as the object.
What property of light is observable on lenses?
Which best describes the image for a thin convex lens that forms whenever the object is at a distance less than one focal length from the lens?
What kind of eyepiece is used in a reflecting telescope?
What is the orientation of the image produced by a Galilean telescope with respect to the object?
What is the purpose of prisms in a binocular?
Which shows the correct sequence of image formation in reflecting telescopes?
I. The light rays refract on the eyepiece producing an enlarged image.
II. Light from the distant object enters the telescope.
III. Light converges after hitting the parabolic mirror.
IV. A plane mirror catches and redirects the light.
Which instrument produces a virtual, larger, and upright image?
Which are TRUE about an electric motor?
I.    It uses magnets to create a circular motion.
II.  It uses magnets to create rotational motion.
III. It converts electrical energy into mechanical energy
IV. It depends on the interaction of magnetic and electric fields.
Which principle works with an electric motor and generator respectively?
In which part of an electric motor is electric current supplied to create
magnetic force?
Based on the principle of electromagnetic induction as applied to generators,
which setup produces the greatest amount of electric current as a magnet is
inserted into a coil of wire? Consider the same strength of the magnet.
According to Fleming’s Left-Hand Rule, in which orientation does current-
carrying wire receive no force of the magnetic field?
